Abstract

A novel waveguide-based 1-D photonic crystal (PhC) microcavity that simultaneously transmits light within the 1310- and 1550-nm wavelength telecommunications bands has been realized. A novel semianalytical model based on wave-vector diagrams was developed to enable rapid optimization of the 1-D PhC with complex periodicity to be etched into an SOI ridge waveguide. Measurements of the multiwavelength transmission characteristics of the resulting complex PhC microcavity revealed transmission peaks at 1321 and 1562 nm with nearly equal transmittivity that is close to the design specification.
