Abstract
The wavelength-selective operation of an optical filter based on a contra-directional photonic waveguide coupler was described. The waveguides were defined as line defects in a two-dimensional triangular photonic crystal fabricated in an InP/GaInAsP heterostructure. The device was characterized using the end-fire method for the drop functionality. It was found that the experimental data are in good agreement with the theoritical results predicted by finite-difference time domain simulations.
