Course Description

The objective of this course is to understand the fundamentals and applications of semiconductor optoelectronic devices. The course starts with introducing some foundation knowledges of semiconductor optoelectronics, such as optical processes in semiconductors and guided wave semiconductor optics. We will then discuss semiconductor optoelectronic devices that have been influencing our life, such as light emitting diodes (LED), lasers, photodetectors and solar cells. Classical materials will be complemented with contemporary subjects. The topics we plan to cover are:
    Optical Processes in Semiconductors
  • Electron-hole pair generation
  • Transition probability in electron-photon interaction
  • Absorption coefficient
  • Various absorption mechanisms
  • Relationship between absorption and emission

    Light Emitting Diodes
  • P-N junction
  • LED principles, structures and overall efficiency
  • Emission spectrum and photon output
  • Frequency response and modulation bandwidth

    Optical Waveguides
  • Modes in planar waveguides
  • Ray-optic approach
  • Electromagnetic wave approach
  • Modes in rectangular waveguides

    Photodetectors and Solar Cells
  • Photoconductors
  • Junction photodiodes
  • Avalanche photodiodes
  • Solar cells

    Lasers: Operating Principles
  • Emission, absorption and gain in a two-level system
  • Emission, absorption and gain in a semiconductor
  • Laser cavity and lasing threshold conditions
  • Laser mode structures

    Lasers: Structures and Properties
  • Threshold current and power output
  • Heterojunction lasers
  • DFB lasers and coupled-mode theory
  • Other laser structures
  • Modulation of lasers
