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…
Image transport through a disordered optical fiber mediated by transverse Anderson localization
Salman Karbasi, Ryan J. Frazier, Karl W. Koch +3
Transverse Anderson localization of light allows localized optical-beam-transport through a transversely-disordered and longitudinally-invariant medium. Its successful implementati…
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…
A modal perspective on the transverse Anderson localization of light in disordered optical lattices
Salman Karbasi, Karl W. Koch, Arash Mafi
We frame the transverse Anderson localization of light in a one-dimensional disordered optical lattice in the language of localized propagating eigenmodes. The modal analysis allow…
Stimulated Raman scattering cascade spanning the wavelength range of 523 to 1750~nm using a graded-index multimode optical fiber
Hamed Pourbeyram, Govind P. Agrawal, Arash Mafi
We report on the generation of a Raman cascade spanning the wavelength range of 523 to 1750 nm wavelength range, in a standard telecommunication graded-index multimode optical fibe…
