ABSTRACT:
Described herein is a multi-channel wavelength division multiplexing (WDM) device including a two-dimensional photonic crystal. The photonic crystal consists of two primary components: (1) a waveguiding element created by line defects formed in the photonic crystal, and (2) frequency-selective elements created by high Q-value microcavities formed in the crystal. The multi-channel WDM system offers a flexible design and high channel density.
