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.

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.
