Compact bends for multi-mode photonic crystal waveguides with high transmission and suppressed modal crosstalk.
نویسندگان
چکیده
We demonstrate an extremely compact bend for a photonic crystal waveguide supporting three spatial modes. The bend exhibits nearly 100% transmission over a relative bandwidth of 1% with less than 1% crosstalk. We show that our design is robust with respect to fabrication errors. Our design method is applied to create a structure consisting of dielectric rods, as well as a structure consisting of air holes in a dielectric background.

We demonstrate highly efficient transmission of light around sharp corners in photonic bandgap waveguides. Numerical simulations reveal complete transmission at certain frequencies, and very high transmission s.95%d over wide frequency ranges. High transmission is observed even for 90± bends with zero radius of curvature, with a maximum transmission of 98% as opposed to 30% for analogous conven...

In this paper, we proposed a novel structure for designing all optical filter based on photonic crystal structure. In designing the proposed filter, we simply employed a point defect localized between input and output waveguides as wavelength selecting part of the filter. The initial form of this filter is capable of selecting optical waves at =1560 nm, the transmission efficiency of the filte...
