The May 2015 American Ceramic Society Bulletin features the work of researchers at MIT, University of Delaware, University of Central Florida, and IRradiance Glass.

This featured article discusses how the current uses of chalcogenide glass in phase change data storage and moldable infrared optics are poised to expand into new applications such as integrated photonics on flexible substrates and on-chip infrared spectroscopic sensors.

The authors comment:

We have shown how we use ChG [chalcogenide] materials’ processing versatility, broadband optical transparency, and monolithic integration capability to enable novel microphotonic functionalities, such as flexible photonics, IR spectroscopic sensing, and multilayer integration. Through smart material engineering, processing design, and device innovation, we have overcome challenges traditionally linked with ChGs.

…This article reveals only the tip of the iceberg compared with what ChG materials have to offer the microphotonics field.
