Title: Solar Photonics for High-Flux Applications


Achieving ultra-high flux with incoherent light requires a combination of an ultra-bright light source and advanced optical design. A sizable fraction of the immense power density at the surface of the sun can be reconstituted here on earth (or just above it in orbit) with suitable optical systems. Using fiber-optic concentrators permits the flexibility of efficiently delivering highly concentrated sunlight to convenient, remote sites and distributing it as desired. Short of exorbitant lasers, no pragmatic high-power alternatives are available. This seminar will cover our progress in the design and experimental realization of ultra-high-flux solar fiber-optic concentrators, with applications to (a) surgery, (b) photovoltaics and (c) nanomaterial synthesis.
