. PHYS3720 OPTOELECTRONICS

Preamble:

In 2009, half of the Nobel Prize for Physics was awarded to Charles K. Kao for ground breaking achievements concerning the transmission of light in fibres for optical communication. Kao’s award marks just one in a long line of Nobel Prizes associated with photonics and optoelectronics, and in the spirit of the award, these discoveries have made a truly profound impact on our every day life. Flat panel displays, high speed Internet, solid-state lighting, digital cameras, medical instrumentation, solar power, we are a society of optoelectronics junkies with an insatiable thirst for bright and shiny gadgets.

Throughout this course we discuss the fundamentals of the field photonics and optoelectronics – the former being the concerned with the manipulation and control of light and the second being the interface between photonics and electronics. We will discuss how light is emitted in semiconductor devices, how it can be transmitted, guided, modulated, switched and detected. Along the way we will consider some of the many applications where optoelectronics has made a significant contribution.
