OEwaves is pleased to announce its newest product, the Stabilized Reference Cavity, to significantly reduce laser noise and laser frequency drift. Based on OEwaves’ patented micro-resonator technology with proprietary packaging techniques, the cavity provides an environmentally insensitive frequency reference with stability of 10^-13 at 1 s in a small form factor.
Lasers used in many applications related to quantum sensors and quantum information systems require high frequency stability over long periods of time. Typical free-running lasers cannot perform at the required stability level by themselves and must be locked to a reference cavity to achieve higher performance. In many applications, frequency stability at the level of 10^-12 over averaging intervals of a few days is required. Conventional reference cavities are made of material with low thermal drift and stabilized for temperature and housed in vacuum packages. These systems are often sensitive to environmental acceleration and vibration, which results in degraded laser performance.
OEwaves’ Stabilized Reference Cavity is based on a variety of crystalline and amorphous materials, whispering-gallery-mode (WGM) micro-resonators featuring optical quality factors greater than 109 and are an excellent for laser stabilization and optical filtering applications. Just millimeters in diameter and compatible with a range of wavelengths from 370 nm to 4500 nm, the Stabilized Reference Cavity provides a tunable reference in a small (14.7 cm x 13 cm x 2.5 cm) and environmentally robust package. Its monolithic integration along with micro-scale mass and volume make the micro-resonator package virtually insensitive to environmental vibrations (less than 10^-10/g), and novel thermal packaging results in a reference for high long-term stability in variable external temperatures.
Virtually every application related to investigating or applying quantum processes for development of quantum computing and quantum sensing employ systems utilizing reference cavities for noise reduction and frequency stabilization of lasers,” said Lute Maleki, CEO of OEwaves. “The complexity of operation, size and cost of reference cavities are amongst the major challenges that OEwaves’ Stabilized Cavity System effectively reduces.”
OEwaves will display the HI-Q series of low noise, high stability laser, THz, and RF products, including the HI-Q Stabilized Reference Cavity, at Photonics West 2025 in San Francisco, Jan. 28 – 30, Booth #3634
