Publication number: 20070236796Abstract: A method for manufacturing a diffusion grating-based optical identification element is provided. The optical identification element includes a known optical substrate, having an optical diffraction grating disposed in the volume of the substrate. A large number of substrates or microbeads having unique identification codes can be manufactured by winding a substrate, such as a fiber, around a polygonal shaped cage/basket to form a fiber ribbon having flat sections. A grating writing station writes one or more gratings into each flat section to form a unique code to this section. Each flat section of fibers of the fiber ribbon is written with the same gratings to provide the same identification code, or alternatively each flat section may be have a different grating(s) written therein so that each section has a different identification code. The fiber ribbon is then removed from the cage and diced to form a groups of optical identification elements, each group having unique optical identification codes.Type: ApplicationFiled: June 16, 2006Publication date: October 11, 2007Inventors: Martin Putnam, John Moon, Paul Szczepanek, Tuo Li, Anthony Rauseo, Joseph Traynor

Patent number: 7126740Abstract: A reconfigurable multifunctional optical device has an optical arrangement for receiving an optical signal, each having optical bands or channels, and a spatial light modulator for reflecting the at least one optical signal provided thereon. The optical arrangement features a free optics configuration with a light dispersion element for spreading each optical signal into one or more respective optical bands or channels for performing separate optical functions on each optical signal. The spatial light modulator includes a micro-mirror device with an array of micro-mirrors, and the respective optical bands or channels reflect off respective micro-mirrors.
