Fabrication of low loss dispersion engineered chalcogenide photonic crystals
Abstract
We demonstrate low loss photonic crystal waveguides in chalcogenide (Ge33As12Se55) glasses. The measured losses are as low as 21dB/cm. We experimentally determine the refractive index of the thin film chalcogenide glass to be n = 2.6 and demonstrate that dispersion engineering can be performed up to a group index of n(g) = 40 in this relatively low refractive index contrast system.
