Overview

The Photonic Systems (SP) department has developed extensive expertise in the design and fabrication of integrated photonic devices based on chalcogenide glasses, exploiting their third-order nonlinear optical properties, the interaction between optical and acoustic waves for Brillouin scattering, and guided luminescence achieved through rare-earth ion doping of these glasses.

In recent years, the team has demonstrated several significant achievements, including:

  • Self-phase modulation (SPM) and four-wave mixing (FWM) in integrated chalcogenide glass waveguides exhibiting strong third-order optical nonlinearities. These waveguides, typically only a few centimetres long and featuring a small effective mode area, provide efficient nonlinear interactions. In addition, integrated chalcogenide glass ring micro-resonators have been used to enhance the nonlinear optical effects within the cavity, leading to a significant improvement in conversion efficiency.
  • Guided mid-infrared luminescence in rare-earth-doped chalcogenide glasses integrated into photonic devices, demonstrating the potential of these materials for integrated mid-infrared light sources.
