We describe a planar photonic circuit in silicon-on-insulator that efficiently generates pairs of non-degenerate photons in a single mode output channel through spontaneous four-wave mixing when pumped with 10's of µW of continuous-wave radiation at wavelengths near 1.5 µm. The structure is based on a set of three coupled photonic crystal microcavities, each of which is judiciously coupled to single...
In this paper a novel THz resonator based on Cherenkov Effect in photonic crystal waveguide is proposed. Cherenkov radiation can be generated by an electron beam crossing with the dispersion curves of photonic crystal waveguide at 8.23 GHz. A microcavity can be constructed by decreasing some radius of rods in the waveguide. The resonance frequency of the microcavity can be adjusted to be consistent...
