Dr. John Burke joined DARPA as a Program Manager in the Microsystems Technology Office (MTO) in August 2017. His research interests include the development of high-stability, low-noise sensors and frequency synthesis to enable new positioning, navigation, and timing (PNT) and remote detection capabilities. He is particularly interested in the integration of modern atomic physics techniques (e.g. laser cooling and trapping) with photonic circuits and atom chips to reduce the complexity, cost, and size of these techniques while increasing their robustness and reliability for use outside of a laboratory environment.
Dr. Young-Kai Chen joined DARPA as a Program Manager in the Microsystems Technology Office (MTO) in September 2017. His research interests include the exploration of innovative technology frontiers in the areas of semiconductor optoelectronic materials, devices, integrated circuits, and advanced system applications for smart sensors, secure broadband wireless, and photonic links.
Microelectromechanical systems, known as MEMS, are ubiquitous in modern military systems such as gyroscopes for navigation, tiny microphones for lightweight radios, and medical biosensors for assessing the wounded. Such applications benefit from the portability, low power, and low cost of MEMS devices. Although the use of MEMS sensors is now commonplace, they still operate many orders of magnitude below their theoretical performance limits. This is due to two obstacles: thermal fluctuations and random quantum fluctuations, a barrier known as the standard quantum limit.
Raman spectroscopy uses lasers to measure molecular vibrations to quickly and accurately identify unknown substances. Ultraviolet (UV) lasers have the optimal wavelength for Raman spectroscopy at stand-off distances, but the Defense Department’s (DoD) current UV-based tactical detection systems are large and expensive and have limited functionality. A new DARPA program seeks technology that may make UV-based detection equipment more readily available in the field.
DARPA yesterday issued a solicitation for proposals responsive to its Spectral Combs from UV to THz (SCOUT) program, which seeks new capabilities for highly sensitive remote detection of multiple biological or chemical agents in liquid or gaseous forms. A proposers day is set for Oct. 15 via webcast.
