Abstract

In this paper, we focus on three issues: 1) proposing a novel photonic crystal waveguide based Symmetric-Mach- Zehnder-type ultrafast all-optical switch using Quantum Dot Semiconductor Optical Amplifier (QD-SOA) and the basic parameters of the photonic crystal waveguide, 2) simulating the general features of the QD-SOA, 3)performance analysis of the all-optical switch. We find that the switching contrast ratio of this kind of all-optical switch has been enhanced due to the superior optical confinement of the photonic crystal waveguide.
