Soliton linear-wave scattering in a Kerr microresonator
Communications Physics, 2022 Tuneable microresonator frequency combs offer low-power, coherent light with a small device footprint. Here, the concept of controlling the comb frequency by detuning the probe phase is translated from photonic crystal fibres to a Kerr microresonator.

Liquid Droplet Microresonators [PDF]
Sensors, 2019 We provide here an overview of passive optical micro-cavities made of droplets in the liquid phase. We focus on resonators that are naturally created and suspended under gravity thanks to interfacial forces, illustrating simple ways to excite whispering-gallery modes in various slow-evaporation liquids using free-space optics.

Dirac solitons in optical microresonators [PDF]
Light: Science & Applications, 2020 AbstractMode-coupling-induced dispersion has been used to engineer microresonators for soliton generation at the edge of the visible band. Here, we show that the optical soliton formed in this way is analogous to optical Bragg solitons and, more generally, to the Dirac soliton in quantum field theory. This optical Dirac soliton is studied theoretically,

Microresonator Brillouin Gyroscope [PDF]
Nonlinear Optics, 2015 Using counter-propagating Brillouin lasers in a high-Q chip-based resonator, rotation measurement with a sensitivity of 15 degree/hour/ Hz is demonstrated. This is close to navigation grade performance and surpasses prior micro-optical systems by 40X.
