A novel polarization channel drop filter based on two dimensional photonic cryst
A novel polarization channel drop filter (PCDF) based on two-dimensional (2D) photonic crystals (PCs) is presented. It consists of two line defect waveguides and two point defect micro-cavities. In the line-defect waveguides, the transverse-electric (TE) and transverse-magnetic (TM) polarization lig
