Compact Mode-Hop Free Narrow Line Turnkey Laser System

OEwaves, Inc., in collaboration with the UCLA trapped-ion quantum computing group, is developing a new class of extended-cavity ultra-stable diode laser systems designed to meet the demanding requirements of next-generation quantum computing and precision metrology.

‍

The system is built on OEwaves’ proprietary self-injection locking technique, which locks a semiconductor laser to a monolithic whispering-gallery-mode resonator (WGMR). This approach provides complete suppression of mode hops over the lifetime of the laser chip, ensuring long-term stability and reliability.

‍

The WGMR is not only used to stabilize the laser’s frequency but also to precisely measure and stabilize its output power to within 10 parts per million over 1 second and beyond. These features are critical for quantum information systems, where ultra-narrow linewidths, frequency stability, and low noise directly determine the performance of trapped-ion qubits and other quantum platforms.

‍

By combining high stability with compact size, weight, and power (SWaP) characteristics, OEwaves’ laser system is engineered to align with the stringent specifications of advanced quantum technologies. Testing of the systems will be conducted by UCLA, ensuring validation in real-world quantum computing experiments.
