Stabilization of an integrated laser with an 8 mL Fabry-Pérot optical reference cavity

Abstract

We present an integrated laser locked to an 8 mL microfabricated optical reference cavity with 1 Hz integrated linewidth, sub-10−14 fractional frequency instability and thermal noise limited performance to ~1 kHz offset. This work assembles the primary components of a fully integrated narrow-linewidth laser source.
