Ultra-Narrow Linewidth Laser Module from OEwaves, Inc.
May 21, 2012
Ultra-Narrow Linewidth Laser Module from OEwaves, Inc., based on a high quality factor (Q) Whispering Gallery Mode (WGM) micro-resonator, offers super-fine instantaneous and dynamic optical spectral linewidth of less than 300Hz and ultra-low phase/frequency noise in a small form factor. The laser is scalable to a variety of wavelengths in C and L bands.
The unique design of the OEwaves Ultra-Narrow Linewidth Laser Module is based on the self-injection locking of a suitable, commercially available, laser diode via a resonant optical feedback from a high-Q WGM micro-resonator. Its monolithically integrated approach, along with micro-scale mass and volume, makes the laser virtually insensitive to environmental vibrations. The laser module is suitable for a broad range of sensing, monitoring, and metrology applications where high resolution, high precision, and absolute accuracy are required.
