Abstract:
Chalcogenide glasses of the As–Se system are promising materials for IR photonics due to their wide transmission window, high refractive index and photosensitivity. Silver incorporation is known to enhance nonlinear refractive index, improve physical parameters and modify short-range order in the glass network.
