We demonstrate spatial multiplexing of two heralded single photon sources created by bi-directionally pumping a single 96 µm photonic crystal waveguide. This enhances the source brightness by 51.2±4.0% whilst maintaining the coincidence to accidental ratio.
We report time-domain measurements of nonlinear dynamics of picosecond pulses in silicon. The dispersion-engineered photonic crystal enables our systematic investigation of dynamic interplay between dispersion, free-carriers, and χ(3) effects for a broad parameter range.
We report the first phase-resolved measurements of nonlinear pulse propagation in silicon photonic devices. These demonstrations indicate soliton-like behavior, despite the presence of two-photon absorption (TPA) and free-carriers impacting the dynamics at 1.55 μm.
We show how slow-light enhanced four-wave mixing in dispersion engineered photonic crystal waveguides can result in ultra-compact devices enabling different applications, namely time-division demultiplexing of 160Gbaud data streams and the generation of correlated photon pairs.
We report FWM (−9dB conversion) in a short (80μm) silicon dispersion engineered slow (c/30) light photonic crystal waveguide through launching a pulsed pump and a CW probe signal.
This paper presents an integrated photonic MEMS switching system. The switching system consist of two perpendicular photonic crystal (PC) surface waveguide joined together to form a waveguide bend. An elliptical micro-mirror driven by a comb drive actuator is positioned with its foci at the end cells of the waveguide bend to provide the switching mechanism. When the position of the mirror is displaced,...
