SC433 - Photodetectors for Optical Communications

Sunday, 19 March
13:30 - 16:30

Short Course Level: Beginner


Joe C. Campbell; University of Virginia, USA

Short Course Description:

This course will focus on p-i-n and avalanche photodiodes. Their performance parameters and the physical effects that determine those parameters will be discussed. Specific topics will include the following:

  • Photodiode fundamentals, e.g., responsivity, dark current, bandwidth, and noise

  • High-speed photodiodes

  • Balanced detectors

  • Normal-incidence versus waveguide photodiodes

  • Photodiodes for Si photonics

  • High-power photodiodes for RF photonic applications

  • Avalanche photodiode concepts

    •  Excess noise

    • Gain-bandwidth product

  • III-V-based and Si-based avalanche photodiodes

  • Single photon detection


Short Course Benefits:

 This course will:

  • Explain the fundamental operation of different types of photodetectors and compare their relative merits. Participants will obtain a broad overview of the photodetectors that are widely deployed in optical communications.

  • Present the state-of-the-art for p-i-n, avalanche, and single-photon photodiodes. Participants will be “up-to-date” with respect to device performance and the, concomitant, limitations.

  • Inform participants of design guidelines and tradeoffs for specific photodetector applications. This will enable participants to specify appropriate detectors.

Short Course Audience:

This course is intended for those interested the fundamentals of photodetectors. For example, what are the factors that determine the maximum bandwidth of a photodiode? What are the current “champion” results and what are the inherent tradeoffs with other performance parameters? The device physics will be presented at a high level although some background in semiconductor devices will be beneficial. The course is intended for those who are new to the area, while providing useful information to workersin the field.
