We demonstrate electro-optic switching using the DC-Kerr effects in a bus-coupled integrated photonic racetrack ring resonator made of Silicon-rich Nitride and find its third order nonlinear susceptibility, χ (3) , of 6x10 -19 m2/v2.
We numerically compare the self-focusing of a Gaussian beam in bulk media to that of guided modes in a cylindrical rod waveguide. We demonstrate delivery of higher power than anticipated from the bulk media calculations.
We demonstrate light localization in a frustrated fractal-like photonic lattice owing multiple flat bands fabricated by femtosecond direct laser writing. We investigate the arising flat bands depending on the singularities of their Bloch wave functions.
We demonstrate the existence of temporal solitons in a laser pumped below its oscillation threshold. Through bifurcation analysis and experimental measurements, we show how the gain saturation impacts this new localized structure.
We model waveguide lattices by vortex-beam arrays in turbulent Kerr media. We investigate localized probe states as flat bands, topological edge states, and Anderson localization. By four-wave mixing, we control the excitation and localization robustness.
