New Developments from Superlum Diodes
On February 3, 2020, Superlum Diodes presented two reports about their development of new SLD devices at the “Optical Coherence Tomography and Coherence Domain Optical Methods in Biomedicine XXIV” Conference. In the first report, called “High power low coherent light sources based on superluminescent diodes”, they describe the most recent results on further success in development of Master Oscillator Power Amplifier – Superluminescent Diode (MOPA-SLD) light sources. The MOPA configuration allows increasing of output power beyond the limits of a single SLD, while simultaneously reducing their sensitivity to optical feedback.
The second report, entitled “Superluminescent diodes of spectral range 730–790 nm based on strained Single Quantum Well (SQW) heterostructure”, describes Superlum’s most recent results on development of a wide spectrum SLD, centered around 750–760 nm. In fact, Superlum successfully acheived spectrum width of up to 50 nm with output power of 5 mW. This is the best combination of output power at 750 nm wavelength. These SLDs may be very useful for further improvement of performance of Optical Coherence Tomography (OCT) systems at 750 nm.
