Monolithic chalcogenide glass waveguide integrated interband cascaded laser

On-chip chalcogenide glass waveguide-integrated mid-infrared PbTe detectors

Chalcogenide glass microsphere laser.

Laser action has been demonstrated in chalcogenide glass microsphere. A sub millimeter neodymium-doped gallium lanthanum sulphide glass sphere was pumped at 808 nm with a laser diode and single and multimode laser action demonstrated at wavelengths between 1075 and 1086 nm. The gallium lanthanum sulphide family of glass offer higher thermal stability compared to other chalcogenide glasses, and ...

Integrated flexible chalcogenide glass photonic devices

Photonic integration on thin flexible plastic substrates is important for emerging applications ranging from the realization of flexible interconnects to conformal sensors applied to the skin. Such devices are traditionally fabricated using pattern transfer, which is complicated and has limited integration capacity. Here, we report a convenient monolithic approach to realize flexible, integrate...

Chalcogenide Glass Materials for Integrated Infrared Photonics

Chalcogenide glasses (ChGs) are amorphous compounds containing the chalcogen elements (S, Se, Te) and exhibit wide infrared transparency windows. They are easy to synthesize in bulk and thin film forms and their compositional flexibility allows tuning of optical properties such as refractive index making them ideal for infrared photonics. We have studied the material attenuation in ChGs that ar...
