Abstract

An optical modulation mechanism based on dynamically shifting the photonic potential barrier of a photonic crystal waveguide is presented. The modulation mechanism is modeled by the one-dimensional quantum tunneling effect using the Schrödinger equation. The calculation results show that the modulation efficiency is 200 times higher than that of the conventional Mach–Zehnder modulator. Based on this innovative concept, an engineering design of an ultracompact silicon photonic crystal waveguide modulator with 10 μ m × 5 μ m footprint is presented.
