This module offers Ultra-Fine instantaneous linewidth of less than 1Hz and ultra-low phase/frequency noise in a compact form factor.

OEwaves Sub-Hz Linewidth laser Module houses a proprietary driver/controller and the OEwaves laser source which is based on an ultra-high quality factor (Q) Whispering Gallery Mode (WGM) micro-resonator.   The laser is scalable to a variety of wavelengths in C band.

The unique technology of the OEwaves Sub-Hz Linewidth Laser Module leverages 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.
