Abstract

We experimentally demonstrate a new class of optical waveguide consisting of a-Si/SiO2 autocloned photonic crystals with modulated lattice structure. The waveguide utilizes the macroscopic form birefringence of photonic crystals and confines light by the difference in the effective refractive index. A monopole modal field with spot diameters of 6.9 μm × 6.5/μm was observed at a wavelength of 1.55 μm. The propagation loss of the waveguide at the wavelength was found to be ∼4.2 dB/mm at most.
