Direct Observation of Thermalization to a Rayleigh-Jeans Distribution in Multimode Optical Fibers
Hamed Pourbeyram, Pavel Sidorenko, Fan Wu +4
Recent years have witnessed a resurgence of interest in nonlinear multimode optical systems where a host of intriguing effects have been observed that are impossible in single-mode…
Mechanisms of Spatiotemporal Mode-Locking
Logan G. Wright, Pavel Sidorenko, Hamed Pourbeyram +6
Mode-locking is a process in which different modes of an optical resonator establish, through nonlinear interactions, stable synchronization. This self-organization underlies light…
Photon Pair Generation with Tailored Frequency Correlations in Graded-Index Multimode Optical Fibers
Hamed Pourbeyram, Arash Mafi
We study theoretically the generation of photon pairs with controlled spectral correlations via the four-wave mixing (FWM) process in graded-index multimode optical fibers (GIMFs).…
Apparent non-conservation of momentum of light due to strongly coupled nonlinear dynamics in a multimode optical fiber
Hamed Pourbeyram, Arash Mafi
The intimate interaction between phase-matched parametric amplification and strong nonlinear mode coupling in a multimode optical fiber results in a saturable spatial mode conversi…
Photon pair generation in multimode optical fibers via intermodal phase-matching
Hamed Pourbeyram, Arash Mafi
We present a detailed study of photon-pair generation in a multimode optical fiber via nonlinear four-wave mixing and intermodal phase-matching. We show that in multimode optical f…
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…
