Invited talk

Dielectric whispering gallery mode (WGM) resonators fabricated from single-crystal materials such as lithium niobate and lithium tantalate combine exceptionally high optical quality factors with strong second-order optical nonlinearities. This means that the resonators therefore provide strong field enhancement and extended interaction times, enabling efficient nonlinear frequency conversion...

In this work, we characterise the frequency stability of a thermally isolated fibre frequency reference in the $0.1\,\mathrm{mHz}$ to $1\,\mathrm{Hz}$ frequency band relevant to laser stabilisation in inter-satellite ranging missions. Inter-satellite ranging using laser interferometry provides the precision of interferometry on a large enough scale that it can be used to probe physical...

Driven optical Kerr resonators have attracted considerable interest as platforms for nonlinear dynamics, frequency comb generation and temporal cavity solitons [1,2]. While microresonators have achieved high quality factors, implementing intra-cavity dispersion control and spectral filtering remains challenging and can introduce loss, increasing the power required. These challenges have...

477. A narrow-linewidth bichromatic external-cavity laser based on a ferroelectric-domain-wall-engineered microresonator

Contributed Oral

Optical microresonators have been successfully employed in self-referenced laser frequency stabilization, narrow-linewidth laser development, and nonlinear optical conversion. To simultaneously carry out these applications with a single microresonator would be highly useful to the development of advanced laser sources with enhanced performances and functionalities.

In this work, we present...
