Abstract
We describe our efforts towards compact ultrahigh-Q 698-nm microcavity stabilization at 1e10-15 frequency instability at 1 second and chip-scale integration for portable precision optical lattice clocks. This advancement is based on state-of-the-art measurements and preliminary results by our team, enabled by the highest quality factor optical resonators (Q f 2e1010) measured to-date. The resonator developed in this STTR will be incorporated into small all-optical atomic clocks. With the targeted frequency stability and accuracy capable of performing near the Cesium clock level or better and at a potential price point of high-end quartz based OCXO, the proposed microresonator-based all-optical clocks will be able to dominate all three Cesium, Rubidium, and mid-high end OCXO based timing sources that range from 1-160 MHz. The applications include wireless networks, defense communications, and navigation.
