Energy conversion efficiency from a high order soliton to fundamental solitons in presence of Raman scattering
Robi Kormokar, Md Hosne Mobarok Shamim, Martin Rochette
We formulate the energy conversion efficiency from a high-order soliton to fundamental solitons by including the influence of interpulse Raman scattering in the fission process. Th…
Far detuned mid-infrared frequency conversion via normal dispersion modulation instability in chalcogenide microwire
Thomas Godin, Yves Combes, Raja Ahmad +3
We report the observation of modulation instability in the mid-infrared spectral region by pumping a hybrid polymer-chalcogenide optical microwire with a femtosecond optical parame…
All chalcogenide Raman parametric Laser, Wavelength Converter and Amplifier in a Single Microwire
Raja Ahmad, Martin Rochette
Compact, power efficient and fiber compatible lasers, wavelength converters and amplifiers are vital ingredients for the future fiber optic systems and networks. Nonlinear optical…
Efficient and broadband optical parametric four wave mixing in chalcogenide-PMMA hybrid microwires
Raja Ahmad, Martin Rochette
The recent development of devices based on novel nonlinear materials like chalcogenides (ChGs), silicon (Si) and other semi-conductors has revolutionized the field of nonlinear pho…
Chalcogenide optical parametric oscillator
Raja Ahmad, Martin Rochette
We demonstrate the first optical parametric oscillator (OPO) based on chalcogenide glass. The parametric gain medium is an As2Se3 chalcogenide microwire coated with a layer of poly…
Photosensitivity at 1550 nm and Bragg grating inscription in As2Se3 microwires
Raja Ahmad, Martin Rochette
We report the first experimental observation of photosensitivity in As2Se3 glass at a wavelength of 1550 nm. We utilize this photosensitivity to induce the first Bragg gratings usi…
