General model of single photon detection
Abstract
The goal of this program is to build a general model for single photon detection. First, this model will allow the comparison between various single photon detector platforms such as single photon avalanche diodes (semiconductor), superconducting nanowire detectors, single electron based photo-transistors (carbon nanotube and quantum dot based) and traditional photomultiplier tubes. It will place limits on achievable performance of these detectors. Secondly, the model will identify the trade-space for new designs in single photon detectors which can overcome the state of the art designs by an order of magnitude. The specific metrics of immediate interest for this model are quantum efficiency, timing jitter, bandwidth and dark count. Initial progress has been made by JacobÕs group in identifying the limitations of conventional photodetector models due to Glauber, Mollow and Mandel. Secondly, ideas of timing jitter and dark count due to vacuum fluctuations which are not present in any previous model has been initiated for simplistic detector models. We have also mapped characteristics of the general model to the superconducting detector which is a promising platform to test these fundamental limits. In this second year, we will address the significant challenge of scaling up the detector model to macroscopic detectors. One of the major goals is to predict new detector platforms which can overcome the state-of-the-art detectors.
