Reflection Characteristics of Coupled-Defect-Type Photonic Crystals
A one-dimensional coupled-defect-type photonic crystal with an attached Au mirror has a wavelength-independent high reflectance over a wide wavelength region. Its delay time for reflected light is more than four times that for transmitted light measured with the mirror removed even though the physical path length for the reflected light is only twice that for the transmitted light. This remarkably long delay is due to the reduction of the field coupling through mirror reflection. The reflection configuration can thus simultaneously provide long delay time and wavelength-independent low loss, properties that are never obtained in a transmission configuration and that are especially advantageous in the device applications of coupled-defect-type photonic crystals.
