III-V semiconductor emitter and detector physics
We have a long standing reputation for research on the physics of semiconductor materials for application in optoelectronic devices.
What we are researching
Much progress continues to be made in understanding the loss of 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 such as:
- Tri-metal alloys and dilute nitride semiconductors for 1.5 micron wavelength telecoms and displays (Prof Stephen Sweeney).
- Quantum dots for temperature insensitive lasers (Prof Stephen Sweeney).
- Carbon nanotubes for non-linear optical materials (Prof Jeremy Allam).
Other applications, such as displays and environmental sensors, operate in different wavelength ranges, and projects include:
