Switching dynamics of dark-pulse Kerr comb states in optical microresonators
Elham Nazemosadat, Attila Fülöp, Óskar B. Helgason +7
Dissipative Kerr solitons are localized structures that exist in optical microresonators. They lead to the formation of microcombs --- chip-scale frequency combs that could facilit…
Design considerations for multi-core optical fibers in nonlinear switching and mode-locking applications
Elham Nazemosadat, Arash Mafi
We explore the practical challenges which should be addressed when designing a multi-core fiber coupler for nonlinear switching or mode-locking applications. The inevitable geometr…
Nonlinear switching in a concentric ring core chalcogenide glass optical fiber for passively mode-locking a fiber laser
Elham Nazemosadat, Arash Mafi
We propose an all-fiber mode-locking device which operates based on nonlinear switching in a novel concentric ring core fiber structure. The design is particularly attractive given…
Saturable absorption in multi-core fiber couplers
Elham Nazemosadat, Arash Mafi
The saturable absorption characteristics of two-, three-, and five-core one-dimensional fiber coupler arrays and the seven-core hexagonal fiber coupler array are investigated. It i…
Nonlinear multimodal interference and saturable absorption using a short graded-index multimode optical fiber
Elham Nazemosadat, Arash Mafi
A detailed investigation of the nonlinear multimodal interference in a short graded-index multimode optical fiber is presented. The analysis is performed for a specific device geom…
