Chalcogenides are promising materials for photonics due to their extraordinary optical properties. However, the biggest barrier to their full technological exploitation is the utilization of these materials in photonic devices with various forms of desired geometries necessitated by unique optical functionalities, such as resonators.
Researchers have now published work exploring new routes for the fabrication of on-chip photonic elements with chalcogenides and considering a low cost high-yield production method with a compatible and extendable integration phase. The study illustrates production of chalcogenide optical cavities embedded in a polymer fiber, on-chip integration of the cavities having spherical, spheroidal, and ellipsoidal boundaries, and results of their optical characterizations.
