Chalcogenide glass fibre‐optics potentially provide a solution for mid‐infrared (mid‐IR) medical endoscopy. It will be shown that chalcogenide glass fibre‐optics could underpin new mid‐IR medical endoscopic systems for real‐time molecular sensing, imaging and analysis of tissue and for fiber laser surgery at new mid‐infrared wavelengths. Moreover, chalcogenide glass fibre‐optic and waveguide devices and systems could provide the key to new mid‐IR communications for molecular sensing to inform decision‐taking in other sectors as diverse as manufacturing, energy, the environment and security. The development and deployment of chalcogenide glasses for mid‐IR photonics over the next decade or so could mirror the complexity and versatility of silica fiber optics developed in the 20th Century for near‐IR photonics. These ide as are developed here and the current status of chalcogenide glass photonics is briefly surveyed.

The success of optical fibers for lightwave communications, employing silica as base material, paved the way to a large use of optical glasses in photonic applications. The field of integrated optics (IO) had been conceived to complement the passive transmissive medium, namely the fibers, with integrated chips, where all the active (signal generation or amplification) and passive (signal addressing and processing) functions could be performed via the guided propagation of light.

Many other optical materials are currently employed in the fabrication of IO circuits, but glass IO still constitutes a branch of photonics capable of offering sophisticated and innovative solutions to many problems ‐ yet involving rather simple technologies. Glass also is a fundamental component of the main current technological platforms for IO, namely silica‐on‐silicon (SOS) and silicon‐on‐insulator (SOI). The developments of fabrication technologies of glass waveguides are briefly surveyed, and examples of devices with excellent performance are presented, together with an analysis of the future perspectives.
