A simple design of 90-degree bend is proposed for cubic photonic crystals. By doubling the density of rods, new types of bends are created. The greatest proposed bend has transmission efficiencies above 99% for a wide frequency range.
A novel approach for modeling photonic crystal circuits is proposed. In this approach, the effective length of photonic crystal waveguide between two devices is estimated. The frequency response of the photonic crystal circuit is modeled as a Fabry-Perot cavity. An example of double 90-degree bend is analyzed by the approach. The results have great agreement with those obtained by finite-difference...
A simple design of 90 degree bend is proposed for cubic photonic crystals. Corner section of bend is modified to have more symmetric guiding field. The transmission efficiencies are above 96% for the bandgap spectrum.
Multimode interference (MMI) coupler with tilted input/output waveguides is proposed. By the self-imaging theory of MMI couplers, the output fields at the end of the multimode region have tilted phase fronts and automatically propagate toward the branching waveguides. The waveguides with layered structure and vertical sidewalls are used to simulate the proposed device. The excess loss is only 0.24...
