300 GHz Wireless Link Based on Whole Comb Modulation of Integrated Kerr Soliton Combs

open access: yesIEEE Photonics Journal, 2023
A Kerr microresonator frequency comb, combined with an ultrafast photodiode, has been utilized to generate millimeter- and terahertz-waves with low-phase-noise.

Soliton blockade in bidirectional microresonators [PDF]

open access: yesOptics Letters, 2020
We report a method to control, disrupt, and restore a regime of unidirectional soliton generation in a bidirectionally pumped ring microresonator. This control, i.e., the soliton blockade, is achieved by tuning the pump frequency of the counterrotating field. The blockade effect is correlated with the emergence of a dark–bright

Model for chaotic dielectric microresonators [PDF]

open access: yesPhysical Review A, 2008
We develop a random-matrix model of two-dimensional dielectric resonators which combines internal wave chaos with the deterministic Fresnel laws for reflection and refraction at the interfaces. The model is used to investigate the statistics of the laser threshold and line width (lifetime and Petermann factor of the resonances) when the resonator is ...

Soliton-comb generation in ring-shaped optical Kerr microresonators under thermal effects

open access: yesResults in Optics, 2023
Soliton combs are nonlinear wavetrains resulting from entanglements of localized waves which may be pulse or kink solitons, forming periodic structures called soliton crystals. In this work we examine the possible generation of soliton-comb structures in

Nonlinear enhanced microresonator gyroscope

open access: yesOptica, 2021
Optical gyroscopes based on the Sagnac effect have been the mainstay of inertial navigation in aerospace and shipping for decades. These gyroscopes are typically realized either as ring-laser gyroscopes (RLGs) or fiber-optic gyroscopes (FOGs). With the recent rapid progress in the field of ultrahigh-quality optical whispering-gallery mode and ring ...

Controlling Microresonator Solitons with the Counter-Propagating Pump

open access: yesPhotonics, 2021
Considering a bidirectionally pumped ring microresonator, we provide a concise derivation of the model equations allowing us to eliminate the repetition rate terms and reduce the nonlinear interaction between the counter-propagating waves to the power ...

Controlling molecular broadband-emission by optical confinement [PDF]

open access: yes, 2008
We investigate experimentally and theoretically the fluorescence emitted by molecular ensembles as well as spatially isolated, single molecules of an organic dye immobilized in a quasi-planar optical microresonator at room temperature.

Soft lithographic fabrication of microresonators [PDF]

open access: yesSPIE Proceedings, 2007
Using ultra-high-Q toroid microcavity masters, soft lithography is applied to fabricate polymer microcavity arrays with Q factors in excess of 106 . This technique produces resonators with material-limited quality factors.
