Dr. Chen Gave Two Talks at NASA Innovation Conference

Dr. Chen attended NASA Innovation 2012 on Oct 12, 2012. She served as the session chair for the Telecom session, and gave two talks on quantum cryptography and DWDM multi-mode switching, respectively. Both talks were well received. Dr. Chen's work on telesurgery was cited by a separate talk from researchers at UT Austin and UH Clear Lake. NASA Innovation 2012 provided a platform for facilitating interdisciplinary collaborations.

Dr. Chen's talk on "Free-Space Quantum-Secure Information Transfer" was a joint work with Dr. Pramode Verma at the University of Oklahoma - Tulsa, and Dr. Subhash Kak at the Oklahoma State University. Dr. Chen discussed the idea of unconditional security using quantum cryptography, which was based on Heisenberg's uncertainty principle and no-cloning theorem, and a robust three-stage quantum cryptography protocol. She presented the prototype implementation and demonstrated a bench-top free-space system, which was established at the University of Oklahoma - Tulsa campus. The work was supported in part by the NSF under grants 1117148, 1117179, and 1117068, and was recently profiled by Science Daily.

Dr. Chen also presented the work on "Packetized DWDM Multimode Switching for Supporting Mission-Critical Applications," which was a joint work with her students, Yiyong Zha, Lei Wang, Shilpa Joshi, and Charles Sou. Dr. Chen presented a promising DWDM multi-mode switching approach where telesurgery and other mission-critical applications can be cost effectively supported by allowing different types of messages within an application to choose from three switching modes: electronic packet switching (EPS), optical burst switching (OBS), and optical circuit switching (OCS).  While using the EPS mode to transfer short command control messages, image and video intensive mission critical applications were expected to benefit from the approach by using the OBS or OCS mode to transfer ultra high bandwidth high definition images and videos. Dr. Chen demonstrated the FPGA prototyping efforts at her Systems Research Laboratory (SRL), and the network testbed, along with a setup that can tele-transport 3D video. The work was supported in part by the National Science Foundation (NSF) under Grants CNS-0708613, 0923481, 0926006, and the Texas Advanced Research Program (ARP) under Grant G096059, along with the generous donation of the DaVinci video development board from Texas Instruments, Inc.
