Observation of topological frequency combs

June 21, 2024
Author(s)
Christopher Flower, Mahmoud Mehrabad, Lida Xu, Gregory Moille, Daniel Suarez-Forero, Yanne Chembo, Sunil Mittal, Kartik Srinivasan, Mohammad Hafezi
On-chip generation of optical frequency combs using nonlinear ring resonators has enabled numerous applications of combs that were otherwise limited to mode-locked lasers. Nevertheless, on-chip frequency combs have relied predominantly on single-ring

Parametrically driven pure-Kerr dissipative solitons in a chip-integrated microcavity

March 14, 2024
Author(s)
Gregory Moille, Miriam Leonhardt, David Paligora, Nicolas Englebert, Francois Leo, Julien Fatome, Kartik Srinivasan, Miro Erkintalo
The discovery that externally-driven nonlinear optical resonators can sustain ultrashort pulses cor- responding to coherent optical frequency combs has enabled landmark advances in applications from telecommunications to sensing. The research focus has

Kerr-induced synchronization of a cavity soliton to an optical reference

December 13, 2023
Author(s)
Gregory Moille, Jordan Stone, Michal J. Chojnacky, Curtis Menyuk, Kartik Srinivasan
The phase-coherent frequency division of a stabilized optical reference laser to the microwave domain is made possible by optical-frequency combs (OFCs). OFC-based clockworks lock one comb tooth to a reference laser, which probes a stable atomic transition

Predicting broadband resonator-waveguide coupling for microresonator frequency combs through fully connected and recurrent neural networks with and without attention mechanism

May 24, 2023
Author(s)
Ergun Simsek, Masoud Soroush, Gregory Moille, Kartik Srinivasan, Curtis Menyuk
Broadband microresonator frequency combs are being intensely pursued for deployable technologies like optical atomic clocks. Spectral features, such as the dispersion in their coupling to an access waveguide, are critical for engineering these devices for

High-performance Kerr microresonator optical parametric oscillator on a silicon chip

January 16, 2023
Author(s)
Edgar Perez, Gregory Moille, Xiyuan Lu, Jordan Stone, Feng Zhou, Kartik Srinivasan
Optical parametric oscillation (OPO) is distinguished by its wavelength access, that is, the ability to flexibly generate coherent laser light at wavelengths that are dramatically different from the pump laser, and in principle bounded solely by energy

Efficient chip-based optical parametric oscillators from 590 nm to 1150 nm

December 2, 2022
Author(s)
Jordan Stone, Xiyuan Lu, Gregory Moille, Kartik Srinivasan
Optical parametric oscillators are a ubiquitous technology used to generate coherent light at frequencies not accessible by conventional laser gain. However, chip-based parametric oscillators operating in the visible spectrum have suffered from pump-to

Ultra-broadband Kerr microcomb through soliton spectral translation

December 14, 2021
Author(s)
Gregory Moille, Edgar Perez, Jordan Stone, Ashutosh Rao, Xiyuan Lu, Tahmid Rahman, Yanne Chembo, Kartik Srinivasan
Broad bandwidth and stable microresonator frequency combs are critical for optical atomic clocks, optical frequency synthesis, dual comb spectroscopy, and a host of other applications that require accurate and precise optical frequency measurements in a

Topological Frequency Combs and Nested Temporal Solitons

August 5, 2021
Author(s)
Sunil Mittal, Gregory Moille, Kartik Srinivasan, Yanne Chembo, Mohammad Hafezi
Recent advances in realizing optical frequency combs using nonlinear parametric processes in integrated photonic resonators have revolutionized on-chip optical clocks, spectroscopy, and multi channel optical communications. At the same time, the

Towards integrated photonic interposers for processing octave-spanning microresonator frequency combs

May 26, 2021
