Redfern Integrated Optics

RIO supplies single frequency narrow linewidth lasers, modules, and subsystems to the clean energy, security, and oil and gas markets.

Redfern Integrated Optics 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.
