Abstract

We show that when a coherent light beam is sent through a passive bistable device, the output beam may exhibit a substantial reduction of photon noise below the shot-noise level, within some frequency range of the noise spectrum. This effect is not limited to the case of a high-finesse cavity and is observable as soon as a bistability turning point is approached. Linear losses have the unexpected consequence of improving the noise-reduction factor at low frequencies.

APS and the Physical Review Editorial Office Continue to Support Researchers

COVID-19 has impacted many institutions and organizations around the world, disrupting the progress of research. Through this difficult time APS and the Physical Review editorial office are fully equipped and actively working to support researchers by continuing to carry out all editorial and peer-review functions and publish research in the journals as well as minimizing disruption to journal access.

We appreciate your continued effort and commitment to helping advance science, and allowing us to publish the best physics journals in the world. And we hope you, and your loved ones, are staying safe and healthy.

Ways to Access APS Journal Articles Off-Campus

Many researchers now find themselves working away from their institutions and, thus, may have trouble accessing the Physical Review journals. To address this, we have been improving access via several different mechanisms. See Off-Campus Access to Physical Review for further instructions.
