Abstract
We have investigated switching properties and especially pulse shape preservation in the process of all-optical switching. To this end, we made two different designs of all-optical switches based on two-dimensional (2D) photonic crystal (PC) waveguides with different dispersive properties and micro-resonators with different quality factors. We realized numerically that all-optical switching without or with marginal temporal pulse distortion can be obtained under precisely chosen conditions on pulse duration and detuning. In particular, the former has to be approximately 2.5 times longer than cavity buildup time and the latter has to be equal to one full width at half maximum of the cavity transmission spectrum.
