Abstract :
Propagation and filtering characteristics of two dimensional (2D) pillar-type photonic crystal waveguide with triangular lattice were simulated by CIP method. The simulation results for Y-shaped branch and the cascaded 1X4 Yshaped branch waveguide were compared with measurements by using a scale model in microwave frequency range from 3.6 to 4.2 GHz. The resonant characteristics for cavities with various lengths were observed in good agreement with the experiment. This structure is applicable as a basic filter component in wavelength division multiplexing (WDM) systems in optical or microwave communication systems.
