Abstract A theoretical analysis is presented for a channel drop tunneling structure composed of a horizonal input channel, a vertical output channel and a multi-mode cavity in a photonic crystal. Criteria for a complete transfer are derived for applications of wavelength devision demultiplexing. The analytical results are verified with a numerical simulation using a finite difference time domain method. The vertical
channel dropping tunneling system makes the demultiplexing device much more compact, as compared to the conventional parallel channel dropping system.
