Nonlinear chalcogenide optical fiber couplers

Optics Express, 2022
We demonstrate chalcogenide optical fiber couplers with a power-dependent coupling coefficient. The couplers are designed and fabricated using an As2Se3 fiber and characterized at a wavelength of 1938 nm, leading to a critical power of 126 W, the lowest ever reported for any optical fiber coupler.

A Geometrical View of Scalar Modulation Instability in Optical Fibers

IEEE Photonics Journal, 2017
Full models of scalar modulation instability (MI) in optical fibers available in the literature usually involve complex formulations. In this paper, we present a novel approach to the analysis of MI in optical fibers by means of a simple geometrical ...

Fast and accurate modelling of nonlinear pulse propagation in graded-index multimode fibers [PDF]

, 2017
We develop a model for the description of nonlinear pulse propagation in multimode optical fibers with a parabolic refractive index profile. It consists in a 1+1D generalized nonlinear Schr\"odinger equation with a periodic nonlinear coefficient, which ...

Generation and manipulation of squeezed states of light in optical networks for quantum communication and computation [PDF]

, 2001
We analyze a fiber-optic component which could find multiple uses in novel information-processing systems utilizing squeezed states of light. Our approach is based on the phenomenon of photon-number squeezing of soliton noise after the soliton has ...
