Abstract: An embossed optical waveguide for light transmission and a method for creating a master and for generating the embossed optical waveguide therefrom. In accordance with an exemplary embodiment of the present invention, a layer of liquid polymer is exposed to energy curing radiation through a mask consisting of clear and opaque areas. The opaque areas in the mask correspond to areas in the liquid polymer which will not be exposed to the curing radiation. During exposure, the areas in the liquid polymer which are exposed through the clear areas in the mask to the curing radiation become cured, or hardened. The areas which are not exposed to the curing radiation do not become cured and subsequently are washed away with a chemical rinse. The resulting structure is a cured layer of polymer having holes pierced through it. The holes pierced through the polymer layer correspond to optical elements formed in the polymer layer. Alternatively, these optical elements can be formed in the layer of polymer after it is cured by reactive ion etching or ion beam milling. The polymer layer which has an index of refraction of 1.55 or greater is bonded to a substrate, which is preferably polypropylene, having an index of refraction of preferably 1.50 or less. Since the refractive index of air is approximately 1.0, the polymer layer is sandwiched between two layers of low refractive index material. The differences between the indices of refraction cause light projected into the polymer layer to be guided in the polymer layer by total internal reflection. Furthermore, once the optical elements have been formed in the polymer layer, it can be used as a master for generating embossments. The embossments are preferably generated by placing liquid polymer in contact with the master, curing it, and separating the cured polymer embossment from the master.

Abstract: An optical signal processor having a monolithic prism supporting one or more channels, and constructed from a first glass block joined to a second glass block at a beam splitter interface. The monolithic prism has thin film beam splitters and filters (such as I and Q filters) either deposited directly on the prism or attached to it. The beam splitter interface, and the thin film beam splitters and filters are arranged relative to each other so that a portion of the return-ranging collimated encoded beam from an external optical sensor is reflected to all the filters. And detectors are connected over the filters to detect particular components of the collimated encoded beam which are passed through the respective filters.

Abstract: An optical device includes an optical waveguide through which light propagates and a micro-resonator structure including an optical sensor. The micro-resonator is configured to resonate at a wavelength of light that may be transmitted through the optical waveguide. When light at that wavelength is transmitted through the optical waveguide, it resonates in the resonator and is detected by the optical sensor to produce an electrical signal. The optical resonator may be a micro-cylinder, disc or ring resonator and may be coupled to the waveguide via evanescent coupling or leaky-mode coupling. Multiple resonators may be implemented proximate to the waveguide to allow multiple wavelengths to be detected. When the waveguide is coupled to a tunable laser, signals provided by the optical sensor may be used to tune the wavelength of the laser.
