SBIR-STTR Award

We propose a set of numerical and analytical tools to address electromagnetic wave propagation in dielectric mirrors and waveguides designed on the principles of omnidirectional reflectivity. Design concepts of the broad frequency range of omnireflectivity will be presented, as well as the deleterious role of imperfections in scattering to the surface and radiation states will be investigated. Omnidirectional reflector technology will have a meaningful commercial effect in multiple markets, including efficient radiation delivery at any desirable wavelengths, in particular, visible and mid IR ranges. Anticipated applications include high power delivery of visible to mid IR radiation for laser surgery, as well as for industrial cutting and welding laser tools. IR spectroscopy for medical diagnostics. IR image transmission and optical communications.

An OmniGuide fiber is a hollow-core fiber which employs a dielectric omnidirectional mirror to keep light confined to its core. These novel fibers are ideally suited for ultra-low loss optical transmission and for flexible delivery of high power lasers. Prior to and during our Phase I effort, we have developed a wide range of tools to simulate the performance of OmniGuide fibers and related structures. This Phase II proposal summarizes our software tool development and sets forth a program to develop a user-friendly, comprehensive, and integrated software package incorporating these tools, suitable for commercialization.
