Key Details

Two-mode squeezed light can surpass shot noise limit in optical sensors

Micro-ring resonators enable squeezed light generation on photonic chips

10x sensitivity gains are predicted for compact, low-loss interferometers

Performance gains drop off rapidly as sensor size & losses increase

Most promising for chip-integrated gyroscopes and accelerometers

AI generated summary

Two-mode squeezed light improves chip-integrated optical sensors

This paper analyzes using two-mode squeezed light generated by four-wave mixing in a micro-ring resonator to enhance the sensitivity of chip-integrated optical sensors like Mach-Zehnder interferometers. The authors derive equations to model the squeezing and use them to show over 10x sensitivity gains are possible for compact, low-loss sensors. However, losses limit the advantage for larger sensors.
