Ultra-Narrow Linewidth Laser
OEwaves Ultra-Narrow Linewidth Laser Source, 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 Source 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 make the laser virtually insensitive to environmental vibrations. The laser is available in standard or custom compact packages installed with either an SMF or PM pigtail fiber, suitable for a broad range of sensing, monitoring, and metrology applications where high resolution, high precision, and absolute accuracy are required.
