Abstract
In two-dimensional photonic crystal waveguide with passive switching function depending on the input light wavelength, the output characteristic is simulated by using frequency dependent FDTD method. For the wide range of input optical wavelength, distribution ratio to output ports is calculated from the electric field profile. For add/drop circuit of wavelength division multiplexing (WDM) optical communication systems, it was found that tuning of add/drop signal wavelength is possible by designing duplexer at branching point with its radius of pillars. Finally, a configuration of drop circuit with simulated structure is proposed.
