摘要： A tunable optical filter utilizes a pair of diffraction gratings and a rotating mirror to achieve a broad filter passband or wavelength bandwidth. By adjusting a small angle between the two diffraction gratings, such as less than approximately 15 degrees, the wavelength bandwidth of the tunable optical filter's passband may be arbitrarily adjusted or set. The two-grating system results in a narrower angular dispersion coefficient than could be achieved through the use of a single grating with similar properties. The narrower angular dispersion in turn results in a broader filter passband or wavelength bandwidth.

摘要： A Gaussian-distributed excitation light beam of an excitation spectrum emitted from an excitation light source enters a light pipe and is there converted to a top-hat spatially distributed excitation beam. The top-hat distributed excitation beam is focused on a phosphor-coated or reflective portion of a surface of an optical wavelength conversion element. Fluoresced and reflected beams travel outward from the wavelength conversion element and re-enter the light pipe to be homogenized during transit through the light pipe. A homogenized fluoresced or reflected beam is relayed to an output as one of a sequence of colors of homogenized light. The functions of Gaussian to top-hat conversion of the excitation beams directed toward the optical conversion element and homogenization of beams directed outward from the optical conversion element are both efficiently performed using a single, shared light pipe.

摘要： A manufacturing method for a grating is disclosed for the angular dispersion of light impinging the grating. The grating comprises tapered structures and cavities. A cavity width and/or corrugation amplitude is varied for achieving a desired grating efficiency according to calculation. A method is disclosed for conveniently creating gratings with variable cavity width and/or corrugation amplitude. The method comprises the step of anisotropically etching a groove pattern into a grating master. Optionally a replica is produced that is complementary to the grating master. By variation of an etching resist pattern, the cavity width of the grating may be varied allowing the optimization towards different efficiency goals.

摘要： A spectrometer that includes a grating that disperses light via Fresnel diffraction according to wavelength onto a sensing area that coincides with an optical axis plane of the grating. The sensing area detects the dispersed light and measures the light intensity associated with each wavelength of the light. Because the spectrometer utilizes Fresnel diffraction, it can be miniaturized and packaged as an integrated circuit.
