"The United States Navy is using and/or experimenting with active, coherent and incoherent sources to detect and localize submarines operated throughout the world. As the U.S. Navy continues to develop and employ active sensors and moves into littoralareas occupied by higher densities of marine mammals, adverse environmental impacts are likely to occur. Recently, in a U.S. Department of Commerce ...

"The goal of the proposed project is to develop and demonstrate an integrated flow control system to reduce aero-optic distortions via control of large-scale shear layer structures and manipulation of the turbulence spectrum in a compressible shear flow.Density fluctuations in a compressible shear layer can produce time-varying index of refraction across the shear layer. Optical systems that must ...

Photonic approaches are attractive for next generation computing and communication systems. In particular, photonic switch matrix is useful for reconfigurable optical interconnection of several high-speed computing systems for missile defense applications.Existing switching device architectures requiring N square cascaded matrix switching elements for N x N non-blocking switching limits the scalab ...

Sinmat Inc. working with University of Florida, proposes to develop an economical and scalable process for fabrication of diamond light emitting diodes (LEDs) that operate in the deep ultraviolet regime. These LEDs are expected to have significant usage inBMDO related activities as compact sources in detection and probes. The formation of diamond LEDs has recently been shown on doped homoepitaxial ...

The terahertz (THz) region of the electromagnetic spectrum is under-utilized for lack of convenient sources. In particular, there is no commercial solid-state far-infrared laser at sub-millimeter wavelengths. The objective of this STTR Phase II project isto deliver well-defined far-infrared solid-state laser products based on the p-Ge active medium. Phase I feasibility demonstrations included elec ...

In this STTR phase I project, a new THz laser mechanism based on p/p+ periodically doped Ge heterostructures will be studied. The intent is to eliminate the optical phonon scattering required in traditional bulk p-Ge lasers, which causes overheating andlimits their duty and gain. A CW laser with 1-4 THz tunability and picosecond pulse capability is anticipated. The new mechanism is based on se ...
