Latest Patents

Zhao-Qing Zhang holds a patent for a "Thin-film large-area coherent light source, filter and amplifier apparatus and method." This invention utilizes lasing at the edge of the reflection band or at a defect state within a thin one-dimensional feedback structure. The result is a large-area, thin-film laser source with transverse dimensions that can exceed the film thickness. The angular confinement of radiation propagating perpendicular to the layers enhances the spatial extent of correlation at the output surface of the thin film. When a pump source induces gain at the lasing threshold, a spatially coherent monochromatic light beam is emitted from the entire gain region.
