NASA has chosen Redfern Integrated Optics to further develop a single-frequency, narrow-linewidth semiconductor laser suitable for spaceflight operation. RIO’s external-cavity semiconductor laser technology is based on the hybrid integration of an indium phosphide (InP) gain chip and a planar lightwave circuit (PLC) with Bragg gratings. Packaged in a standard 14-pin compact “butterfly” package, the laser is characterized by a single-frequency output in the 1550-nm spectral region with a linewidth less than 2 kHz, low phase noise, low relative intensity noise (RIN), and high immunity to vibrations in a wide range of operating temperatures.
