We propose the development of an atomically referenced visible spectroscopy-grade PIC laser operating at 689 nm which will provide a visible PIC-based oscillator with absolute atomically referenced frequency stability capable of reaching the part per trillion level.
Compact clock lasers at wavelengths for Sr clock transitions that are directly specified in call for proposals. Specifically roadmaps: TA-8.1.3: Optical Components (reliable laser systems) and TA-8.1.5: Lasers (reliable laser system w/ long lifetime) with ultimate SWaP improvement due to full on-chip integration.
Compact sensing, navigation, and timekeeping. Low-cSWAP inertial guidance devices and gravity gradiometers, interaction-free atomtronic circuits, portable quantum sensors and clocks, new probes of surface physics, hybrid quantum technologies, and chip-based matter wave SQUIDs.
