Self-switching Kerr oscillations of counter-propagating light in microresonators
Michael T. M. Woodley, Lewis Hill, Leonardo Del Bino +2
We report the experimental observation of oscillatory antiphase switching between counter-propagating light beams in Kerr ring microresonators, including the emergence of periodic…
Logic Gates based on Interaction of Counterpropagating Light in Microresonators
Niall Moroney, Leonardo Del Bino, Michael T. M. Woodley +5
Optical logic has the potential to replace electronics with photonic circuits in applications for which optic-to-electronic conversion is impractical and for integrated all-optical…
Spectral Extension and Synchronisation of Microcombs in a Single Microresonator
Shuangyou Zhang, Jonathan Silver, Pascal DelHaye
We demonstrate that the optical spectrum of a soliton microcomb generated in a microresonator can be coherently extended by using bichromatic pumping: one pump with a frequency in…
Optical memories and switching dynamics of counterpropagating light states in microresonators
Leonardo Del Bino, Niall Moroney, Pascal Del'Haye
The Kerr nonlinearity can be a key enabler for many digital photonic circuits as it allows access to bistable states needed for all-optical memories and switches. A common techniqu…
Coherent suppression of backscattering in optical microresonators
Andreas Ø. Svela, Jonathan M. Silver, Leonardo Del Bino +4
As light propagates along a waveguide, a fraction of the field can be reflected by Rayleigh scatterers. In high-quality-factor whispering-gallery-mode microresonators, this intrins…
A Nonlinear Enhanced Microresonator Gyroscope
Jonathan M. Silver, Leonardo Del Bino, Michael T. M. Woodley +6
We demonstrate a novel optical microresonator gyroscope whose responsivity to rotation is enhanced by a factor of around by operating close to the critical point of a sponta…
