摘要：
A selective wet-etching method for micro-fabricating As2S3 glass ridge waveguides, using CS2 solution with iodine as an oxidising reactant, has been developed. The proposed method is based on photoinduced changes in chalcogenide glasses, and therefore can be free of photomasks and photoresists. The optical properties of such etched ridge waveguides have been tested and they exhibit a more than 2 dB/cm loss reduction compared to laser direct-written channel waveguides.
