Abstract

Summary form only given. Introducing a line defect into a photonic crystal can create localized states within the photonic band gap of the crystal. Such a defect behaves as a waveguide, where the confinement of the light occurs via the photonic band gap (PBG) rather than total internal reflection. Aside from some recent optical experiments, most qualitative studies of photonic crystal waveguides have been done at microwave frequencies. We report on measurement of the mid-IR transmission spectrum of waveguides in two-dimensional (2D) macroporous silicon photonic crystals.
