III-V semiconductor emitter and detector physics

The Photonics Group has a long standing reputation for research on the physics of semiconductor materials for application in optoelectronic devices. Much progress continues to be made in understanding the loss mechanisms in semiconductor laser diodes, and optimising devices for applications in optical communications at near-infrared wavelengths.

Improved performance in these applications may be realised in new materials; we are studying:

Other applications, such as displays and environmental sensors, operate in different wavelength ranges, and projects include:
