We demonstrate the possibility of fabricating an infrared transmitting waveguide by burying fiber in chalcogenide glasses. Two highly mature chalcogenide glasses are used for these experiments. GASIR glass from Umicore IR Glass, Olen, Belgium, with the composition of Ge22As20Se58 is used to draw fibers that are then buried in an As2S3 glass substrate. The glasses we used are compatible, and we obtained a high quality interface. We performed a transmission test with a CO2 laser at 9:3 μm. The potential for extremely low loss planar waveguides is discussed.
