Invited talk

Optical frequency combs generated through cascaded four-wave mixing offer a flexible route to broadband sources with widely-spaced spectral lines. Their spectral profile depends strongly on phase matching, motivating approaches that extend dispersion control beyond fixed waveguide designs. This presentation traces the development of programmable dispersion as a tool for controlling nonlinear...

Fibre-optic gyroscopes (FOGs) provide a clear and accessible demonstration of relativistic physics suitable for the undergraduate laboratory. Although the rotational and propagation speeds involved are far below the speed of light, the operation of a fibre-optic gyroscope depends on the relativistic transformation of the speed of light in a moving medium. In this paper, we compare the...

The ability to control two lasers at different wavelengths such that their relative frequency difference remains consistent is a desirable trait for continuous variable and twin-field quantum key distribution systems, and stable terahertz signal generation through photomixing. A standard approach for this is to use an optical frequency comb, which provides a phase stable optical reference...

350. Microcomb-enabled parallelized PRBS LiDAR for time and frequency congested environments

LiDAR sensors with fast sample rates and precise spatial resolution are an important enabling technology for autonomous driving and unmanned aerial vehicles. With ubiquitous use of the technology, robustness to temporal and spectral congestion is becoming a key criterion for LiDAR systems. FMCW LiDAR using chaotic micro-combs has previously been shown to be a promising approach for accurate...

Contributed Oral

Optical frequency combs (OFCs) bridge the optical to the microwave (electronic) domain and enable frequency counting in optical atomic clocks (OACs) and low noise microwave synthesis, amongst other applications. Using the OFC directly for spectroscopy is challenging due to the low power per comb line (typically nanowatts to microwatts) and the narrow line spacing of fibre-based OFCs; this...
