Abstract :
In this paper, we report on preliminary results of the study of two dimensional photonic band gap extended microcavity in a ridge waveguide with mode matching technique for good efficiency coupling between the input and output waveguides and the photonic crystal (PhC) structure. Transmission improvement above 70% at a wavelength of 1.55 μm is reported with respect to the transmittivity achieved with conventional PhC structures without any matching feature.
