Redfern Integrated Optics (RIO), provider of low noise external cavity lasers and subsystems, has secured a Phase 1 Small Business Innovation Research (SBIR) contract from NASA to enhance its innovative narrow-linewidth, single-frequency semiconductor laser designed for spaceflight mission.
Redfern Integrated Optics’ patented external-cavity semiconductor laser technique is developed by the hybrid amalgamation of a planar lightwave circuit (PLC) and an InP gain chip with Bragg gratings. Enclosed in a regular 14-pin small butterfly package, the performance of the laser is denoted by a single-frequency output within the 1550 nm spectral region and less than 2 kHz linewidth, less relative intensity noise (RIN), low phase noise and high resistance to vibrations under various operating temperature range.
RIO's PLANEX, RIO-Grande and ORION lasers are suitable for ultra-resolution spectroscopy, dispersed temperature, LIDAR, acoustic or strain fiber optic monitoring, remote sensing and accurate metrology applications where precision and lifetime durability over challenging field conditions and ultra resolution are vital.
The Chairman, Chief Executive Officer and President at Redfern Integrated Optics, Radu Barsan said that the company’s semiconductor laser is ideal for space missions as it already complies with Telcordia standards and is installed in the fiber optic sensing and LIDAR applications.
