EXPERIMENTAL STUDY OF BENT SiC OPTICAL WAVEGUIDES

摘要

Bending losses of curved plasma-enhanced chemical Vapour (PECVD) Silicon Carbide (SiC) waveguides are studied experimentally,. We show that properly designed curved sections generate less 0.5 dB/rad for both TE and TM polarisations. We also investigate the wavelength dependency and show that the bending losses decrease with wavelength in the visible range.
