Superluminescent Diodes (SLDs)




  • Broadband Emission Centered at 1050, 1280, 1310, or 1550 nm
  • Near-Gaussian Spectrum
  • Low Ripple
  • Butterfly or DIL Package

Features

  • Center Wavelength at 1050, 1280, 1310, or 1550 nm
  • Typical Bandwidths Ranging from 40 to 110 nm
  • Butterfly or DIL Package
  • Pigtailed with 1.5 m of SM or PM Fiber
  • FC/APC Connector
  • Integrated TEC and Thermistor

Superluminescent Diodes (SLDs) are excellent high-power, broadband light sources that are ideal for use in applications such as Optical Coherence Tomography (OCT) Imaging Systems and Fiber Optic Gyroscopes (FOG). The Dual In-Line- (DIL) and Butterfly-packaged SLDs offered here are Indium Phosphide (InP) devices manufactured by Thorlabs' Quantum Electronics (TQE).

Each device has an integrated thermoelectric cooler (TEC) and thermistor to ensure output stability. The output is coupled into an SM or PM fiber terminated with an FC/APC connector. The SLDs in DIL packages have integrated photodiodes for monitoring the device output. We also offer some of these SLDs in our XL line. These SLDs, denoted with the suffix XL, are hand-picked parts that demonstrate highly desirable specifications such as increased bandwidth and power.
