SC337 Single Photon Detection with Avalanche Photodiode (LS&C)

Mark Itzler, Princeton Lightwave Inc., USA
Sunday, 27 October 2013, 16:00-19:00

Course Description: The ability to detect a single photon is the ultimate level of sensitivity in the measurement of optical radiation.  There has been growing interest in single photon detectors in response to emerging applications for which single photon counting is an enabling capability. In many cases, these applications involve physical processes in which only a very small number of photons -- often just one -- are available for detection.  In other instances, it is the quantum properties of a single photon that are exploited, and these applications are critically dependent on the means for sensing individual photons.  This course will provide an overview of single photon detector technologies along with a summary of relevant applications.  In addition to surveying various single photon detector technologies, the course material will provide an in-depth focus on avalanche photodiodes since these detectors are often the most practical solution -- from perspectives including performance, ease-of-use, cost, and commercial availability -- for single photon detection.  The presentation of design considerations and performance attributes should be useful to end users of this detector technology as well as to those who desire a qualitative understanding of the principles of single photon avalanche photodiode design.  Ancillary operational considerations such as required support electronics will also be covered.  The course will conclude with an assessment of future prospects for single photon detector technologies.

Benefits and Learning Objectives
After completion of this short course the participant will be able to:

  • Identify a variety of applications that rely on single photon counting

  • Compare different single photon detection technologies and choose the most appropriate detector for a given application

  • Manage tradeoffs in single photon detector performance parameters to define optimized operating conditions

  • Describe the fundamental design principles of single photon avalanche photodiodes

  • Summarize different options for the support electronics -- especially quenching circuitry -- involved in the operation of single photon avalanche photodiodes

  • Evaluate the state-of-the-art and future directions in single photon detection

Intended Audience: This course is intended for engineers and scientists who wish to understand the basics of single photon detection.  The presentation of detector design considerations and performance attributes should be useful to potential end users of single photon detector technologies as well as to those who desire a qualitative understanding of the principles of single photon avalanche photodiode design.  Some familiarity with the basics of semiconductor photodetectors will be helpful but is not essential.

Instructor Biography: Dr. Mark A. Itzler is CEO & CTO at Princeton Lightwave, Inc.  Prior to joining PLI in 2003, he was the CTO at the Epitaxx Division of JDS Uniphase.  He has been active in the design and commercialization of avalanche photodiode technology since 1996 and has focused on its application to single photon counting for the past nine years.  Dr. Itzler currently chairs the Conference on Advanced Photon Counting Techniques at the SPIE Defense, Security + Sensing Symposium and is a past Chair of the IEEE Photonics Society Technical Committee on Photodetectors and Imaging.  He is also an Associate Editor of IEEE Photonics Technology Letters and a Fellow of the IEEE.
 

SC407 High Harmonic Generation and Attosecond Pulses (ASSL)

Eric Constant, CELIA, France
Sunday, 27 October 2013, 16:00-19:00
 
Course Level:  Advanced beginner

Course Description: High order harmonic generation (HHG) is currently receiving lot of interest as this laser-like XUV source has many attractive properties such as large spectral extend, short pulse duration down to the attosecond level (1 as = 10-18 s) , good spatial coherence and automatic synchronization with ultrashort visible/IR pulses. During this course, I will present the main characteristics of the high order harmonic generation in gases and the underlying physical mechanisms both at the microscopic level (involving intense laser- atom interaction) and macroscopic level (where the coherent buildup of the emission defines the XUV beam characteristics). I will relate this XUV pulse generation with the necessary characteristics of the ultrashort laser systems that can be used for HHG and show that these characteristics can now be fulfilled by various laser architectures. I will also present the techniques that are used to characterize the ultrashort XUV pulses both in the spectral and temporal domains.  In a second part of the course, I will focus on the temporal characteristics of the high order harmonic beam and show how attosecond pulses can be generated and controlled through HHG. This part will include a brief overview of femtosecond pulse post compression and carrier envelop phase stabilization that are commonly used  in our community.  This course will also be illustrated with applications of HHG and attosecond pulses.

Benefit and Learning Objectives: This course will enable participants to understand the characteristics and properties of ultrashort XUV sources based on high order harmonic generation and to learn how these sources can be generated, controlled and used experimentally.
 

This course should enable participates to: 

  • Define the general properties of the XUV harmonic sources
