Thorlabs offers NIR SLDs with center wavelengths from 770 nm to 1610 nm (see the Quick Links table to the right). The butterfly-packaged SLDs offered here up to 1100 nm are gallium arsenide (GaAs) substrate based and the rest are indium phosphide (InP) devices.

Each device is built into a 14-pin butterfly package with an integrated thermoelectric cooler (TEC) and thermistor to ensure output stability. The output is coupled into an SM or PM fiber terminated with a 2.0 mm narrow key FC/APC connector. Please note that optical feedback can diminish the output power or damage the SLD. We do not recommend using these SLDs with components that are prone to back reflections, such as FC/PC connectors. The SLD1220x, SLD1310x, SLD1325, SLD1330x, and SLD1410x superluminescent diodes incorporate an integrated optical isolator. If you are interested in an SLD at a different wavelength with an integrated isolator, please contact Tech Support with inquiries.

Full Specifications are available by clicking on the Specs tab above. Each SLD is shipped with an individualized product data sheet, which includes information on the spectrum and operating parameters of the device. Test data for a specific SLD can be requested by contacting Tech Support.

For spectra comparison graphs, see the Spectral Comparison tab. The SLDs featured on this page have either a near-Gaussian or flat-top optical spectrum. The calculation for the center wavelength differs with these two spectral shapes. Please see the Specs tab for center wavelength calculations.

Thorlabs is able to provide low-ripple SLDs with custom wavelengths or higher power diodes. Please note that the engineering design and wafer manufacturing costs involved make the purchase of low quantities very costly. For a quote on custom SLDs, please contact Tech Support. A selection of the SLDs sold here are also available as benchtop sources. For more information, see the Selection Guide tab.

Due to the nature of producing superluminescent diodes with ultra wide bandwidths, some of the SLDs sold below have spectral shapes that are near gaussian, while others have a shape with a flattened top. This difference in spectral shape demands two different methods of defining center wavelength in order to provide an accurate description of the diode.

Near-Guassian Center Wavelength Definition
The center wavelength for devices with a near-gaussian spectral shape is defined by an average weighted by the relative amplitude and may not correspond to peak power or the FWHM center wavelength due to the variability of the spectrum shape. For a given Optical Spectrum Analyzer (OSA) trace:

Weighted Average

where

  • CW is the Specified Center Wavelength
  • Xi is the Wavelength of a Trace Data Point
  • Yi is the Amplitude of a Trace Data Point

Flat-Top Center Wavelength Definition
The center wavelength for devices with a flat-top spectral shape is defined by the midpoint between the two wavelengths located at 3 dB below the maximum intensity point on the spectrum. For a given OSA trace:

Weighted Average

where

  • CW is the Specified Center Wavelength
  • XR_3dB is the Right Wavelength Edge of the 3 dB Bandwidth
  • XL_3dB is the Left Wavelength Edge of the 3 dB Bandwidth

 

SLD Specifications

Note that these specifications are given as guidelines. The characterization sheet shipped with each SLD provides the minimum, maximum, and recommended operating parameters and specifications specific to that device. The ASE Power specification is the output from the fiber pigtail.

  • Values are typical unless otherwise noted.
  • Basic superluminescent diode characteristics can be measured by increasing current (I) while measuring the device voltage (V) and light output (L). The resulting data is usually referred to as an LIV curve.
  • For more information on how the center wavelength for our NIR SLDs is defined, please see the Specs tab on the NIR Superluminescent Diodes presentation.

Hi, could you give any information about the polarization contrast (PER)? Specifically I'm interested in SLD810S. Thank you.
cdolbashian  (posted 2024-03-15 04:31:55.0)
Thank you for reaching out to us with this inquiry. While the SLD will be nominally polarized from the chip, we unfortunately do not characterize the polarization of these devices, as they are SM coupled, and the polarization will depend on the stress on the fiber as well as the ambient temperature the fiber experiences. For this reason, you can use a Paddle polarization controller to set your polarization state. I have contacted you directly to discuss this further.

is pin13, case connected to anode pin 10?
jpolaris  (posted 2024-01-23 07:43:54.0)
Thank you for contacting Thorlabs. Yes, for these NIR superluminescent diodes, case ground pin 13 and SLD anode pin 10 are connected. As in, they are not isolated with respect to one another in the circuit.

Can you provide the performance data (output spectrum, LIV plot, and gain ripple) of SLD830S-A20?
Bob Holland  (posted 2023-08-10 10:01:15.507)
I am just curious, why are products such as the 1050S-A60 not classified with a Laser Safety warning, when sold. (as are all of the visible compact lasers of only a few mW) A power of 60mW emitted from a SM fiber end would definitely be hazardous when viewed with an instrument. Is this possibly because it is considered a "sub-component" and not a powered turn-key system? Thanks in advance for your opinion here.

Thank you for contacting Thorlabs. You are exactly right. The output from sources such as SLD1050S-A60 will be dependent on the conditions under which they are driven. A turnkey system can be assigned a classification because there are defined bounds to the drive conditions, and thus also to the output from the source.

Is there a PCB design manual? I'm not sure what to connect to pins 1, 2, 5, 10, 11, 13, and 14

Thanks for reaching out to Thorlabs. For each butterfly diode, e.g. SLD1005S, the performance data and spec sheet can be found on our product page, which includes the pinout for the diode. Our CLD1015 can serve as a laser mount, laser driver, and TEC driver. Our LM14S2 mount can also be used for connection if running the diode in Anode-Grounded configuration with a separate driver. I have reached out directly to discuss this further.

Does the SLD830S-A10W emits the light with polarization within fiber? Do we need "polarization scrambler" in the path?
jgreschler  (posted 2022-07-15 09:31:43.0)
Thank you for reaching out to Thorlabs. The SLD chip output is polarized, however the emission of the single mode fiber is going to depend on temperature and stress on the fiber. You can control these factors and the polarization state using a paddle controller to obtain your desired output polarization state.

Hello! I try to use SLD830S-A10W with driver CLD1015. We should check whether the Steinhart-Hart A,B and C of SLD is right. So, we want to know the SHH A,B and C values of SLD830S-A10W as they are not mentioned in the Spec Sheet Could you let me know?

Pierre Senée  (posted 2022-03-07 08:59:56.137)
Dear Sir or Madam, I am using the SLD850S-A20W for research purposes in microscopy. The 850 nm beam from the source is injected in my system with a P3-780A-FC-1 fiber. I recently incorporated the BST17 beamsplitter in my system and I have the following issue : When the fiber is moved (even very slightly) the transmitted power through the beamsplitter varies. I believe this is due to the polarisation of the light which varies with the bending and coiling of the fiber. (the transmission coefficient of the beamsplitter varies quite a lot with the polarization). This is quite a big issue for my system as I would like a steady transmitted intensity. Would you know if an easy solution for this issue exist ? Best regards, Pierre Senée

Thank you for reaching out to us Pierre. In troubleshooting cases like this, it is very important to consider all potential sources of noise and instability in your system. To begin something like this, it is helpful to remove each component in your experimental setup and verify which element is the source of the instability. I have reached out to you with some additional troubleshooting steps and look forward to hearing from you soon.

Hello! I try to use SLD810S with driver CLD1015. According to manual YouTube video(https://www.youtube.com/watch?v=LAixCOso-FE&t=874s), we should check whether the Steinhart-Hart A,B and C of SLD is right. However, as we didn't get the spec sheet of SLD810S. Also, in thorlab website, only SLD1325 had these values. So, we want to know the SHH A,B and C values of SLD810S. Could you let me know?

Hello Zhen, thank you for contacting Thorlabs. The LDC220C can certainly be used to drive our NIR SLEDs with the LM14S2 mount and TED200C driver, but please note that the noise will be greater than that of the CLD1015.
Byeong-Kwan YANG  (posted 2020-11-13 05:31:56.183)
This is YANG, Byeong-Kwan of Jiny Photonics in S. Korea. I purchased SLD830S-A20W (serial number: SLD-41707-40313.2.A04) and I am testing it now. When measured with a low resolution spectrometer (USB4000), its spectrum comes out smoothly. We are currently manufacturing a high-resolution spectroscopy (spectral resolution 0.04 nm), and if I measure the spectrum with the spectrometer being manufactured, high-frequency components are measured. I don't have a spectrum analyzer, so I can't get a high resolution spectrum to verify. Can I get the high resolution spectrum of the SLD830S-A20W?
YLohia  (posted 2020-11-13 02:02:12.0)

Hi. I'm also interested in intensity noise. Do you have any measurements for your SLDs that you could share?
cdaly  (posted 2014-04-09 03:32:58.0)
Response from Chris at Thorlabs: We will contact you directly information on the relative noise intensity. Laser diodes generally show a peak in the RIN curve from some resonance effects of the cavity, whereas ASE sources do not. Noise at various frequencies(frequency of intensity noise, not wavelength of the light) in ASE source would be more flat.

jlow  (posted 2014-01-30 11:51:35.0)
Response from Jeremy at Thorlabs: The intensity at 950nm is estimated to be around -25dB lower than the peak. It falls sharply after that to around -60dB at 850nm. Since you did not leave your contact info, can you contact me at techsupport@thorlabs.com please? I can provide a spectral scan for a SLD1050S unit.
bdada  (posted 2012-04-25 10:50:00.0)
Response from Buki at Thorlabs to alexandru.serb05: Thank you for your feedback. Gain ripple is not intensity noise. It is due to interference between two SLD facets such that, on its spectrum, you will see variation of the amplitude of the spectrum density vs. wavelength. SLD noise only depends its bandwidth and in principle, it is frequency independent. We have done some studies on that and I have contacted you with the results.
alexandru.serb05  (posted 2012-04-24 05:00:41.0)
Hallo, I just need to ask a couple of questions: 1) Could you please explain to me the concept of gain ripple? Is it variations in average output intensity: a) between different LEDs? b) between different frequency bins within the same LED? c) at each frequency bin over time within the same LED? d) Something completely different? 2) Is there a way I can see some noise plots for all these products? It would be particularly useful if I had access to such data and comparable data relating to the pigtailed laser diode range of products you offer. Noise vs frequency as measured by the same photodetector capturing the entire outgoing beam at a specificed power output is the sort of plot I have in my mind, but anything that yields meaningful comparative noise data will do. Note: both laser and non-laser diode may be assumed to be driven by a controller + TEC, but without feedback stabilisation if such data is available. Introducing feedback brings along a whole array of other parameters and will only make comparisons more difficult... Thanks.
