Abstract
We proposed a new double-resonant cavity four-channel add–drop filter based on the in-plane type two-dimensional (2D) photonic crystal with square lattice. Through this novel double-resonant cavity, WDM signals can be coupled in or out of the bus waveguide with 100% add–drop efficiency while completely prohibiting cross talk between the bus and the add–drop waveguides for all other wavelengths. This device could be used as an optical add–drop multiplexer (OADM) in coarse wavelength division multiplexing (CWDM) applications.
