Abstract

Polarization-independent waveguiding at 1.32 and 1.54 μm was observed in single-crystal S1−xyGexCy grown nearly lattice matched upon Si(100) by chemical vapor deposition. Losses were <5 dB/cm at 1.54 μm. Experiments indicate that the band gap of three SiGeC alloy waveguides was in the 0.93–0.99-eV range, in agreement with theory.
