Basics of semiconductor optoelectronic devices including photodiodes, light-emitting diodes, laser diodes, CCDs. Applications include solar cells, displays, photodetection, and optical communications.
Credits: 1 hour, 2 hours seat time
Co-requisite or Prerequisite: OSE 4410 (Optoelectronics)
Detailed Description:
This lab course is associated with the theory course on the same topic (OSE 44410) on introduction to the principles, design, and applications of optoelectronic devices. Basic specification of key optoelectronic devices, including photodiodes, LEDs, diode lasers, LED and LCD displays are experimentally obtained by the students. The experiments include both DC (static) and AC (dynamic) characteristics of the devices and will emphasize both the electrical and optical figures of merit. The advantages and disadvantages of various types of diode-based photodetectors (APD vs. PIN) and light sources (LEDs vs. lasers) are experimentally quantitatively studies in the lab.
List of Experiments:
- Photodiodes:
- Light-current characteristics of APD and PINs
- Photovoltaic effect
- LEDs :
- Light-current characteristics and power efficiency
- Emission spectrum
- Laser diodes
- Light-current characteristics
- Subthreshold and above threshold output spectra
- Slope and differential quantumefficiencies
- Characteristic temperature
- Small-, large-signal and pulse-code modulation and differential gain
- LED numerical displays
- LCD numerical displays
Learning Outcomes:
Upon completing this lab course, the students will become experimentally familiar with various optoelectronic devices and know how to:
- Bias photodiodes, LEDs and lasers in different modes of operation
- Obtain light-current characteristics of the devices and extract basic figures of merits
- Measure more advanced specifications such as modulation bandwidth and emission spectra
- Bias and operate LED and LCD types of displays and their comparisons
- Independently operate key photonic measurement pieces of equipment such as optical spectrum analyzers
