Laser Cavity-Soliton Micro-Combs
Hualong Bao,Andrew Cooper,Maxwell Rowley,Luigi Di Lauro,Juan Sebastian Totero Gongora,Sai T. Chu,Brent E. Little,Gian-Luca Oppo,Roberto Morandotti,David J. Moss,Benjamin Wetzel,Marco Peccianti,Alessia Pasquazi +12 more
TL;DR: In this paper, a micro-comb laser cavity-solitons, an intrinsically highly-efficient, background free class of solitary waves, is proposed for the generation and control of self-localised pulses in microcavities.

Laser cavity-soliton microcombs
Hualong Bao,Andrew Cooper,Maxwell Rowley,Luigi Di Lauro,Juan Sebastian Totero Gongora,Sai T. Chu,Brent E. Little,Gian-Luca Oppo,Roberto Morandotti,Roberto Morandotti,Roberto Morandotti,David J. Moss,Benjamin Wetzel,Marco Peccianti,Alessia Pasquazi +14 more
TL;DR: In this paper, a 50nm wide bright microcavity-based soliton combs with a mode efficiency of 75% was presented, more than one order of magnitude lower than the Lugiato-Lefever soliton power threshold.
Proceedings ArticleDOI
Type II microcomb generation in a filter-driven four wave mixing laser
Andrew Cooper,Hualong Bao,Sai T. Chu,Dave J. Moss,Roberto Morandotti,Brent E. Little,Marco Peccianti,Alessia Pasquazi +7 more
TL;DR: In this paper, a well-known route to comb generation starts from the modulation instability (MI) of the pump, which generates coherent lines spaced by more than one free spectral range of the microcavity.
Journal ArticleDOI
Type-II micro-comb generation in a filter-driven four wave mixing laser [Invited]
Hualong Bao,Andrew Cooper,Sai T. Chu,Dave J. Moss,Roberto Morandotti,Brent E. Little,Marco Peccianti,Alessia Pasquazi +7 more
TL;DR: In this article, the authors demonstrate the generation of highly coherent Type-II micro-combs based on a micro-resonator nested in a fiber cavity loop, known as the filter-driven four wave mixing (FD-FWM) laser scheme.
Proceedings ArticleDOI
Burst-mode operation of a 655GHz mode locked laser based on an 11-th order microring resonator
Li Jin,Alessia Pasquazi,K. S. Tsang,Victor Ho,Marco Peccianti,Andrew Cooper,Lucia Caspani,Marcello Ferrera,Brent E. Little,David J. Moss,Roberto Morandotti,Sai T. Chu +11 more
TL;DR: In this article, a burst mode envelope of 40 ps at 7.12 MHz was achieved by exploiting an integrated 11th order micro-ring resonator, which achieved stable operation with a mode-locked train of pulses at 650 GHz.
