摘要

Abstract

Narrow linewidth stabilized lasers are central to precision applications that operate across the visible to short-wave infrared wavelengths

including optical clocks

quantum sensing and computing

ultra-low noise microwave

generation

and fiber sensing. Today

these spectrally pure sources are realized using multiple external cavity tabletop lasers locked to bulk-optic free-space reference cavities. Integration of this technology will enable portable precision applications with improved reliability and robustness. Here

we report wavelength-flexible design and operation

over more than an octave span

of an integrated coil-resonator-stabilized Brillouin laser architecture. Leveraging a versatile two-stage noise reduction approach

we achieve low linewidths and high stability with chip-scale laser designs based on the ultra-low-loss

CMOS-compatible silicon nitride platform. We report operation at 674 and 698 nm for applications to strontium neutral and trapped-ion clocks

quantum sensing and computing

and at 1550 nm for applications to fiber sensing and ultra-low phase noise microwave generation. Over this range we demonstrate frequency noise reduction from 1 to 10 MHz resulting in 1.0–17 Hz fundamental and 181–630 Hz integral linewidths and an Allan deviation of 6.5 × 10

−13

at 1 ms for 674 nm

6.0 × 10

−13

at 15 ms for 698 nm

and 2.6 × 10

−13

at 15 ms for 1550 nm. This work demonstrates the lowest fundamental and integral linewidths and highest stability achieved to date for stabilized Brillouin lasers with integrated coil-resonator references

with over an order of magnitude improvement in the visible wavelength range. These results unlock the potential of integrated

ultra-low-phase-noise stabilized lasers for precision applications and further integration in systems-on-chip solutions.
