Redfern Integrated Optics Inc.

Redfern Integrated Optics (RIO), Inc. develops and manufactures laser sources based on proprietary PLANEX™ (Planar External Cavity Laser) technology, which enables cost-effective high performance for sensing and other applications.

The RIO planar ECL consists of a gain chip and a planar lightwave circuit (PLC) with Bragg grating which forms the laser cavity. This has significant advantages, such as narrow spectral linewidth, low phase noise and RIN, optimized chirp, low wavelength sensitivity to temperature and bias current, and low power consumption.

RIO's product lines include 1550nm CW narrow-linewidth lasers and long-reach 2.5-10 Gbps directly modulated TOSAs, with DWDM wavelength stability, at low cost, small size and with low power dissipation.
