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.

SPECS

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
X_i is the Wavelength of a Trace Data Point
Y_i 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
X_{R_3dB} is the Right Wavelength Edge of the 3 dB Bandwidth
X_{L_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.

These SLDs are designed to be used in OCT imaging applications. They have a low gain ripple no larger than 0.6 dB (RMS) and a typical ripple value 0.2 dB (RMS). They are packaged with an integrated TEC and thermistor for temperature control, as well as an optical isolator which provides 30 dB of isolation for enhanced optical stability. More information on Thorlabs' SLDs for OCT systems can be found here. Note that the bandwidth will decrease as the current is decreased; bandwidth specifications below are specified at the operating current.
