Invited talk

Following a decade of success through LIGO and Virgo’s observations of compact binary coalescences, gravitational wave astronomy is now widely recognized as a key tool in our continued efforts to understand the Universe and our place within it.

Far from resting on their laurels though, the gravitational wave community is forging ahead with major plans for the future. The proposed “ultimate...

Passive Kerr frequency combs generated within coherently driven cavities have been shown to have huge application potential, ranging from spectroscopy to ultra-fast imaging. While the generation of high-quality Kerr combs in the near-infrared is easily achievable, the same cannot be said for visible and near-visible Kerr comb generation. Due to the strong normal dispersion of nearly all...

Spectrographs used for exoplanet characterisation often rely on highly stable Fabry-Perot interferometers for real time calibration. Designers of Fabry-Perot calibration systems commonly use modified Airy functions to model changes to mirror coatings, surface irregularities, and other sources of phase shift to identify and characterise sources of mode drift. Physical calibration systems have...

Contributed Oral

Optical frequency combs generated in driven passive cavities are generally associated with cavity solitons, arising from the balance of gain and loss and of Kerr nonlinearity and anomalous quadratic dispersion [1]. Their formation is successfully described by the Lugiato–Lefever equation (LLE) [2]. Cavity solitons often organize into soliton crystals (SCs), ordered arrays of closely spaced...

Single-longitudinal-mode (SLM) Raman lasers are emerging as promising light sources that combine very low frequency noise with the potential for watt-level output powers, making them attractive for quantum applications. Previous Raman systems from our group have demonstrated intrinsic linewidths down to the hertz level, with measurements limited by instrument noise. However, such...
