Featured Projects

The wide range of applications of photonics extends from the communications and entertainment systems in homes to uses in biology, quantum computation, energy generation, medicine and environmental sensing. At the CRPuO, our world-class researchers are working several ongoing projects. The results of the activities of the CRPuO will assist with:

  • Developing technology that will power the world with low cost, environmentally friendly, and highly efficient concentrated solar cells
  • Greater global access through enabling broadband information access (internet, telephony, cable)
  • Working in areas allowing for communicating sound, vision and touch over optical networks
