Abstract
Measurements on a single-line defectphotonic crystal waveguide demonstrate propagation losses as low as 140 cm −1 and coupling efficiency to a ridge access guide increased from 20% to 50% thanks to a tapered access. These results are obtained by analyzing the internal cavities created by residual reflections, hence, requiring a single sample. They are nevertheless crosschecked by measurements on distinct samples by the Fabry–Pérot resonance method.Keywords
