Leading Global Supplier of Single Frequency Narrow Linewidth Lasers, Modules and Subsystems Passes Rigorous Testing

Redfern Integrated Optics, Inc. (RIO) today announced the completion of the first phase of a reliability testing program of its planar external cavity narrow-linewidth low-noise PLANEX™ lasers for space applications. The program included extensive environmental stress tests performed by RIO and by LGS Innovations(the subsidiary of Alcatel-Lucent), a NASA prime contractor.

RIO’s proprietary external-cavity semiconductor lasers are packaged in the standard 14-pin compact “butterfly” package, and provide a single-frequency output in the 1550 nm spectral region with a linewidth less than 2kHz, low phase noise, low relative intensity noise (RIN), high immunity to vibrations, over a wide range of ambient temperatures. RIO’s lasers are already qualified to Telcordia optical communications standards and are widely deployed in LIDAR and fiber optic sensing applications. The inherent reliability and stability of the PLANEX™ lasers make them ideal candidates for aerospace applications.

“NASA selected RIO’s PLANEX lasers for their unique combination of mission critical performance with a compact and robust design,” said Alfonso Piccirilli, Technical Manger at LGS. “LGS performed environmental stress testing and concluded that performance and reliability testing done to date has indicated that the PLANEX™ laser is robust and well positioned to meet the qualification requirements of NASA missions.”

“Environmental testing of RIO PLANEX™ lasers for NASA was demanding and included a large number of wide temperature range cycles at various conditions and enhanced hermeticity testing,” added Dr. Georgios Margaritis, RIO’s Director of Operations, Quality and Reliability. “All lasers were produced on RIO’s manufacturing line without special selection and passed all tests without failures. The results confirm the high reliability of RIO’s products, that is critical not only for future aerospace applications, but also for our current OEM customers.”
