Journal ArticleDOI
Azimuthal Turing Patterns, Bright and Dark Cavity Solitons in Kerr Combs Generated With Whispering-Gallery-Mode Resonators
Aurélien Coillet,Irina Balakireva,Rémi Henriet,Khaldoun Saleh,Laurent Larger,John M. Dudley,Curtis R. Menyuk,Yanne K. Chembo +7 more
TL;DR: In this article, the formation of cavity solitons in crystalline whispering-gallery-mode disk resonators that are pumped in different dispersion regimes is investigated, and the authors use the Lugiato-Lefever spatiotemporal formalism to investigate the temporal dynamics leading to the formation and emergence of these azimuthal solitions, as well as the emergence of Turing patterns.
Journal ArticleDOI
Optimally coherent Kerr combs generated with crystalline whispering gallery mode resonators for ultrahigh capacity fiber communications.
J. Pfeifle,Aurélien Coillet,Rémi Henriet,Khaldoun Saleh,Philipp Schindler,Claudius Weimann,Wolfgang Freude,Irina Balakireva,Laurent Larger,Christian Koos,Yanne K. Chembo +10 more
TL;DR: It is demonstrated that Turing patterns, which correspond to the so-called primary combs in the spectral domain, are optimally coherent in the sense that for the same pump power they provide the most robust carriers for coherent data transmission in fiber communications using advanced modulation formats.
Journal ArticleDOI
Phase noise measurement of a narrow linewidth CW laser using delay line approaches
TL;DR: Two different laser phase noise measurement techniques are compared and an extraction of the laser linewidth using computer-aided design tools is performed, confirming the interest of the low-cost technique.
Journal ArticleDOI
Cascaded Brillouin lasing in monolithic barium fluoride whispering gallery mode resonators
Guoping Lin,Souleymane Diallo,Khaldoun Saleh,Romain Martinenghi,Jean-Charles Beugnot,Thibaut Sylvestre,Yanne K. Chembo +6 more
TL;DR: In this article, the authors reported the observation of stimulated Brillouin scattering and lasing at 1550nm in barium fluoride (BaF2) crystal with ultra-high quality (Q) factor monolithic whispering gallery mode mm-size disk resonators.
Journal ArticleDOI
Phase noise performance comparison between optoelectronic oscillators based on optical delay lines and whispering gallery mode resonators.
Khaldoun Saleh,Rémi Henriet,Souleymane Diallo,Guoping Lin,Romain Martinenghi,Irina Balakireva,Patrice Salzenstein,Aurélien Coillet,Yanne K. Chembo +8 more
TL;DR: This work investigates the phase noise performance of optoelectronic oscillators when the optical energy storage elements are in the following three configurations: a high-Q whispering gallery mode resonator, an optical delay-line and a combination of both elements.
