A photonic-plasmonic integration scheme was devised to displace the defect-mode field of a photonic crystal (PC) slab cavity from the spatial center to the surface of the slab. The device was constructed by placing an isolated metallic structure on the top surface of a missing-hole defect in the PC. Excitation of the metal's surface plasmon resonance mode by the PC cavity's defect mode was investigated using a three-dimensional plane wave transfer matrix method. It was revealed that using the PC cavity could minimize the background field around the metal, significantly enhancing the field intensity contrast between the metal and surrounding dielectric.
We systematically investigate realization of super narrow-pass-band and super narrow-transmission-angle filters with
one-dimensional defective photonic crystal hetero-structures through the transfer-matrix method. The structure consists
of a few different defective one-dimensional photonic crystal blocks. The influence of the relative bandwidth of the
defective layer, the number of periods, and the ratio of index of the high index material to the low index material in the
structures were studied. We find that when the relative width factor m and n of the defective layers are even numbers,
relatively narrower pass-angle will be achieved. When the number of periods of the structures increases, the pass-angle
will decrease exponentially. When the number of periods reaches 12, the pass-angle gets to be less than 0.002 degree. In
addition, higher ratio of the two indices in the structures corresponds to smaller transmission angle and narrower
wavelength pass-band.
