Journal ArticleDOI
Nonlinear multimodal interference and saturable absorption using a short graded-index multimode optical fiber
Elham Nazemosadat,Arash Mafi +1 more
TL;DR: In this paper, a detailed investigation of the nonlinear multimodal interference in a short graded-index multimode optical fiber is presented, where the light is coupled in and out of the multimode fiber via single-mode fibers.
Journal ArticleDOI
Phase matching for spontaneous frequency conversion via four-wave mixing in graded-index multimode optical fibers
TL;DR: In this article, a detailed analysis of phase matching conditions in graded-index multimode optical fibers is presented, which is relevant mainly for spontaneous frequency conversion and photon pair generation via FWM, when the signal and idler are generated at large frequency separations from the pump.
Journal ArticleDOI
Detailed investigation of intermodal four-wave mixing in SMF-28: blue-red generation from green.
TL;DR: The predictive power and limitations of a theoretical model are highlighted to explain the experimental results for a process that relies on the amplification of quantum vacuum energy over more than 11 orders of magnitude.
Journal ArticleDOI
Switching dynamics of dark-pulse Kerr frequency comb states in optical microresonators
Elham Nazemosadat,Attila Fülöp,Oskar B. Helgason,Pei-Hsun Wang,Yi Xuan,Daniel E. Leaird,Minghao Qi,Enrique Silvestre,Andrew M. Weiner,Victor Torres-Company +9 more
TL;DR: In this article, the formation of dark-pulse Kerr combs is associated with the appearance of another resonance, a feature that has never been observed for dark pulses and is ascribed to soliton behavior.
Journal ArticleDOI
Nonlinear switching in multicore versus multimode waveguide junctions for mode-locked laser applications
Elham Nazemosadat,Arash Mafi +1 more
TL;DR: The main differences in nonlinear switching behavior between multicore versus multimode waveguide couplers are highlighted and the key reasons are identified behind higher switching power requirements and lower switching quality in multimode nonlinear coupler.
