ABOUT

Redfern Integrated Optics (RIO), Inc. develops and manufactures optical transmitters based on proprietary PLANEX™ (Planar External Cavity Laser) technology, which enables high performance at low cost for various applications.

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

RIO's cost-effective high performance PLANEX™ products include:

• CW 1550nm laser sources in 14-pin butterfly package with very narrow linewidth, low phase noise, low RIN, and excellent wavelength stability for fiber optic sensing, test and measurements and other industrial and military applications
  
  
• Directly modulated 1550nm XMD TOSA devices for long reach, TDM and DWDM C-band, excellent wavelength stability and low power dissipation with data rates of up to 10 Gbps for telecom and datacom applications
