In this paper we will discuss DARPA's interest in short-wavelength ultraviolet (UV) semiconductor emitters, and their potential application to biological agent detection, as well as other military applications. Specifically, there is considerable interest in miniaturizing 'detect-to-warn' bio-sensors. Currently, DoD is developing a sub-system known as the Biological Aerosol Warning System (BAWS) for the Joint Biological Point Detection System (JBPDS). The BAWS works on the principle of laser induced fluorescence (LIF), in which an ultraviolet laser beam interacts with a flowing particle stream such that fluorescence is generated when particles containing biological agents are present. A future goal is the reduction in size, weight, power consumption, and cost of this system. Semiconductor UV optical sources afford the opportunity to achieve these new miniaturized system goals.
