Abstract:
A hybrid one-dimensional photonic crystal waveguide--a slab waveguide surrounded by one-dimensional photonic crystal with omnidirectional reflection bands, is presented; the transmission/reflection characteristics of the hybrid waveguides with a semi-cylinder defect are investigated by numerical simulation. Calculated results indicate that, as long as the semi-cylinder radius is appropriately adjusted, the high reflectance of 96.7%, nearly zero transmittance and low loss of 3% can be observed. The hybrid waveguide with a semi-cylinder defect can be used as a waveguide reflector. The simple and compact waveguide reflector is expected to be applied to highly dense photonic integrated circuits after further research.
