Abstract

This letter reports demonstration of optically induced signal modulation in two-dimensional photonic crystal (PhC) optical intersections. High resolution and high aspect ratio PhC was fabricated for optical communication wavelengths. Besides characterization of the silicon PhC static properties, dynamic modulations through spatially localized applications of high intensity pump radiation were also demonstrated to yield normalized modulations of 15 dB for incident intensity of 70 MW/cm² - corresponding well with first principles simulations. The effective modulation range and pump limit of the method were therefore determined and the potential of such a modulation scheme as a practical means of developing tunable PhC devices was realized.
