Analysis of a Modified Y-Branch CWDM Demultiplexer Based on Photonic Crystal Structure

Journal of Microwaves, Optoelectronics and Electromagnetic Applications
This paper attempts to investigate the design of a modified Y-shaped demultiplexer based on photonic crystal. The designed structure is used to select four telecommunication wavelengths. In our design, four resonant cavities (RC)are utilized.
