We demonstrate the fabrication of high Q Ge_28Sb_12Se_60 ring resonators in an all
chalcogenide platform through electron-beam lithography, lift-off and thermal reflow. We …

Chalcogenides are a group of amorphous glasses that are transparent from the near to far
infrared and have a high third order optical nonlinearity. We demonstrate the …

There is a great need for compact, broadband, high efficiency infrared light sources for
numerous applications. Integrated nonlinear photonics based on chalcogenide glass …
