HI-Q® ULTRA-NARROW LINEWIDTH LASERS
HI-Q® Lasers have empowered scientists and engineers to accelerate the development of optical clocks, control qubits and quantum operations with higher fidelity, and detect smaller and faster vibrations with enhanced resolution.
In advanced fields such as quantum sensing, quantum computing, fiber optic sensing, photon-Doppler velocimetry, and biomechanics, these ultra-low noise lasers are driving faster development cycles and delivering superior performance.
The lasers achieve this by using self-injection locking, where a laser diode is locked to a crystalline whispering gallery mode resonator with a typical Q-factor exceeding one billion. This mechanism results in an exceptionally narrow Lorentzian linewidth.
Thanks to the compact design of the laser cavity, the system is remarkably resistant to vibrations — a resilience demonstrated in OEwaves' photonic systems operating aboard rockets and in other high-vibration environments.

Test and Measurement
The unique technology of the OEwaves HI-Q® laser leverages the self-injection locking capability of a suitable commercially available laser diode via 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.
