Abstract :
A practical and detailed analysis of light propagation around a 90 /spl deg/C bend corner in a photonic crystal slab is presented. Transmision spectra of samples with different designs are compared for better understanding of the transmission efficiency and the losses. Points where the reflection occurs can be identified by Fourier transformation of the transmission spectrum. The fringe contrast of the Fabry-Perot modulation may also allow the evaluation of the losses in the waveguide by calculating the loss coefficient.
