Shallow Junction Photonics: Black Silicon Enhanced Photodetectors
SiOnyx has developed a next generation silicon based photodetector with spectral sensitivity from 350 to 1550 nm making silicon a very attractive infrared detector material system. These detectors exhibit photoconductive gain, routinely generating responsivities in excess of 100 A/W (>100x standard silicon detectors) throughout the visible, NIR and SWIR bands. We enhance the spectral sensitivity of silicon in these devices by employing a femtosecond laser doping processing on a CMOS compatible platform. The energetic of the laser process enable the formation of a new material with these remarkable properties. Operating at a mere 3V the devices made from this material rival avalanche photodiodes at much lower power and bias. When applied to imaging platforms, this detector will enhance visible light imaging and will enable silicon to become the next generation nightvision detector, outperforming InGaAs, Ge, and image intensifiers in nearly all nighttime light conditions.
Dr. Pralle is the VP of Business Development at SiOnyx. Prior to this he was the General Manager and VP of Engineering at ICx Technologies' Photonics division where he spent 8 years developing photonic crystal MEMS infrared emitters and bolometer sensors from initial device inception to high volume production. This development required cross functional technology integration including photonic bandgap physics, optics, MEMS mechanical device design, and analog electrical circuitry. As part of this past activity he was PI on or contributed to multiple SBIR and government funded research programs from NSF, NIH, DOE and others. Dr. Pralle holds a PhD from the University of Illinois at Urbana-Champaign and BS from Cornell University, both in Materials Science. As a graduate student he focused on self assembling strategies for supramolecular aggregates in order to spontaneously fabricate functional devices.

General Information on NES/OSA Meetings
If the meeting must be canceled for any reason, we will try to call you at the phone number you leave with your reservation. Official notice of cancellation will be on our answering machine.
We have to pay for the dinners reserved as of the Tuesday before the meeting, so no-shows eat into our cash reserve. If you will not be able to attend, please let us know as early as possible. Otherwise, no-shows will be billed.
NOTE: The extra $5.00 of the non-member dinner fee can be used toward membership dues if the nonmember joins and pays dues for the current year at the meeting.
