PLANEX Laser Diode – Ultra Low Noise (phase / RIN) and Single Frequency fiber Laser Source.

The PLANEX™ product series are high performance and industry-proven single frequency External Cavity Lasers (ECL) based on RIO’s proprietary planar technology – PLANEX™. The PLANEX laser consists of a gain chip and a planar lightwave circuit (PLC) that includes a Bragg grating. The coupling of these components forms a cavity with significant benefits, with up to 20 mW output power, very low RIN, ultra-low phase noise and narrow linewidth, and very low wavelength sensitivity to bias current and temperature.

The PLANEX’s higher output power, low noise and ultra narrow linewidth ideally position this semiconductor optical solution for multiple applications where absolute accuracy, lifetime reliability over-demanding field conditions, and high resolution are vital, such as remote sensing, distributed temperature, strain, or acoustic fiber optic monitoring, high resolution spectroscopy, LIDAR and other precision metrology applications.
