From rogue waves to solitons
Amdad Chowdury, Wonkeun Chang, Marco Battiato
Using a generalized nonlinear Schrödinger equation, we investigate the transformation of a fundamental rogue wave to a collection of solitons. Taking the third-order dispersion, se…
Higher-order rogue wave fission under the effects of third-order dispersion, self-steepening and self-frequency shift
Amdad Chowdury, Wonkeun Chang, Marco Battiato
Using the generalised nonlinear Schrödinger equation, we investigate how the effect of third-order dispersion, self-steepening, and Raman-induced-self-frequency shift have an impac…
Microjoule-level mid-infrared femtosecond pulse generation in hollow-core fibres
Ang Deng, Trivikramarao Gavara, Muhammad Rosdi Abu Hassan +2
We demonstrate a fibre-based approach that generates mid-infrared femtosecond pulses in the 3-4 μm spectral region with microjoule-level single pulse energy. This is realised in a…
Empirical formulae for hollow-core antiresonant fibers: dispersion and effective mode area
Imran Hasan, Nail Akhmediev, Wonkeun Chang
We present empirical formulae that can provide dispersion and average effective area of the fundamental mode in hollow-core antiresonant fibers. The formulae draw on the structural…
Vacuum-UV to IR supercontinuum in hydrogen-filled photonic crystal fiber
Federico Belli, Amir Abdolvand, Wonkeun Chang +2
Although supercontinuum sources are readily available for the visible and near infrared, and recently also for the mid-IR, many areas of biology, chemistry and physics would benefi…
High Pressure Gases in Hollow Core Photonic Crystal Fiber:A New Nonlinear Medium
Mohiudeen Azhar, Gordon Wong, Wonkeun Chang +2
The effective Kerr nonlinearity of hollow-core kagome-style photonic crystal fiber (PCF) filled with argon gas increases over 100 times when the pressure is increased from 1 to 150…
