Degenerate four-wave mixing in a CPT-symmetric coupler with intermodal dispersion
Nguyen Duc Anh Quan, Do Duc Tho, Marek Trippenbach +3
Four-wave mixing provides a simple setting in which dispersion, nonlinearity, and non-Hermiticity compete to select resonant energy-transfer channels. We study degenerate four-wave…

Analysis of High-Contrast All-Optical Dual Wavelength Switching in Asymmetric Dual-Core Fibers
Le Xuan The Tai, Mattia Longobucco, Nguyen Viet Hung +8
We systematically present experimental and theoretical results for the dual-wavelength switching of 1560 nm, 75 fs signal pulses (SPs) driven by 1030 nm, 270 fs control pulses (CPs…
