Abstract

Interface states are known to exist at the surface of an appropriately structured Bragg reflector. If such reflectors are present on the surfaces of two prisms separated by a narrow gap, the evanescently coupled interface states can interact to produce a pair of very narrow transmission lines, the separation of which can be adjusted by varying the size of the gap between the two prisms. Thus, although only a single cavity is involved, the spectral properties of the system are similar to those of a dual-cavity photonic microstructure. In addition to other potential applications, we propose that such a structure could form the basis of an adjustable beat-frequency emitter in the terahertz regime.
