Opto-electronics

Reading: Sze chapter 9 or Singh chapter 11 or Thuselt chapter 4

    For the exam:
  • Be able to describe how a light emitting diode, solar cell, and a laser diode work. Know what determines the color of a LED or laser.
  • Be able to explain total internal reflection and how it is used in an optical fiber and why it can be a problem coupling light out of an LED.
  • Know the difference between spontaneous emission and stimulated emission. Know why a laser diode has a threshold current.
  • Be able to describe light absorption in a semiconductor and what this has to do with the bandgap.
