Learning from Nature: Sensing the Absolute Minimum Light Intensity

Abstract: High-performance single photon detectors are regarded as enabling technology in many fields, including optical tomography, quantum cryptography, and landmine detection, since they can detect the absolute minimum light intensity, or a single photon. Despite several decades of intense research on semiconductor single photon detectors, current devices suffer from high noise and low sensitivity. In this talk, I will show the method that Nature has chosen for light detection, and explain why it is orders of magnitude better than the manmade devices. I would then explain a novel type of light detector that we have developed based on the light detection mechanism in the rod cells in the eye. Finally, I present recent results from this device that outperforms some of the best existing detectors by order of magnitude.

Hooman Mohseni received his Ph.D. degree in Electrical Engineering from Northwestern University, where his work focused on novel type-II superlattices and heterostructures. He joined Sarnoff Corporation in 2001, where he was a technology leader for several government, domestic, and international commercial projects. He joined Northwestern University in 2004 as a faculty member. Dr. Mohseni is the recipient of the best student paper award from International Semiconductor Device Research Symposium 1999, the Best Ph.D. Thesis Award from Robert McCormick School of Engineering in 2001, was a Searle Junior Fellow in 2005, recipient of National Science Foundation CARRER Award in 2006, was selected by NSF as one of the 14 US members of the US-Japan Young Scientist Exchange Program on Nanotechnology in 2006, and received Young Faculty Award from Defense Advanced Research Projects Agency (DARPA) in 2007. He has served at the Technical Program Committee of several major conferences including IEEE Laser Electro-Optics Society (LEOS) Annual Meetings and SPIE Photonic West. He has also serves as the Program Committee Co-chair for the SPIE Security and Defense Symposium in 2007. Dr. Mohseni has published over 40 articles in refereed journals, a chapter of a book on IR detectors, and holds two patents and four patent applications. His publications have been cited more than 250 times in the peer-reviewed journals.
