摘要： A grating trim retarder fabricated from a form-birefringent multi-layer dielectric stack including at least one anti-reflection coating and supported on a transparent substrate is provided. The form-birefringent dielectric stack includes an axially-inhomogeneous element in the form of a −C-plate grating and a transversely-inhomogeneous element in the form of an A-plate grating. Each of the −C-plate and the A-plate gratings are fabricated with dimensions to form a zeroth order sub-wavelength grating structure. Fabricating the grating trim retarder with anti-reflection coatings and/or a segment where the −C-plate and A-plate grating overlap enables the in-plane and out-of-plane retardances to be tailored independently according to the desired application.

摘要： An oblique angle deposition is used to provide an A-plate optical retarder having at least one dense, form-birefringent layer. According to one embodiment, the dense, form-birefringent layer(s) are deposited as part of an FBAR stack to provide an all-dielectric full-function A/−C-plate trim retarder for LCD birefringence compensation. Advantageously, the dense structure of the full-function A/−C-plate trim retarder offers high durability and/or stability, thus making it well suited for providing polarization compensation in high light flux polarization-based projection systems.

摘要： A variable optical filter is disclosed including a bandpass filter and a blocking filter. The bandpass filter includes a stack of alternating first and second layers, and the blocking filter includes a stack of alternating third and fourth layers. The first, second and fourth materials each comprise different materials, so that a refractive index of the first material is smaller than a refractive index of the second material, which is smaller than a refractive index of the fourth material; while an absorption coefficient of the second material is smaller than an absorption coefficient of the fourth material. The materials can be selected to ensure high index contrast in the blocking filter and low optical losses in the bandpass filter. The first to fourth layers can be deposited directly on a photodetector array.

摘要： A portable spectrometer device includes an illumination source for directing at a sample, and a tapered light pipe (TLP) for capturing light interacting with the sample at a first focal ratio and for delivering the light at a second focal ratio lower than the first focal ratio. A linearly variable filter (LVF) separates the captured light into a spectrum of constituent wavelength signals; and a detector array, including a plurality of pixels, each of the plurality of pixels disposed to receive at least a portion of a plurality of the constituent wavelength signals provides a power reading for each constituent wavelength. Preferably, the TLP is lensed at one end, and recessed in a protective boot with stepped inner walls. The gap between the TLP and LVF is minimized to further enhance resolution and robustness.

摘要： The invention relates to a wafer scale process for the manufacture of optical waveguide devices, and particularly for the manufacture of ridge waveguide devices, and the improved waveguides made thereby. The present invention has found a process for achieving sub-micron control of an optical waveguiding layer thickness by providing a dimensionally stable wafer assembly into which adhesive can be introduced without altering the planar relationship between a carrier wafer and an optically transmissive wafer in wafer scale manufacture. This process permits wafer scale manufacture of optical waveguide devices including thin optically transmissive layers. A pattern of spacer pedestals is created by a deposition and etch back, or by a surface etch process to precisely reference surface information from a master surface to a carrier wafer to a thin optically transmissive wafer. The tolerance achievable in accordance with this process provides consistent yield across the wafer.

摘要： A thermally stabilized optical filter device includes a multilayer optical bandpass filter on a transparent substrate, with the transparent substrate being composed of a material having a first coefficient of thermal expansion. An encasement surrounds the transparent substrate such that the bandpass filter is exposed for transmission of predetermined optical wavelengths there through. The encasement is composed of a material having a second coefficient of thermal expansion that is different than the first coefficient of thermal expansion. The encasement provides thermal stability to the optical properties of the bandpass filter by compensating for changes in the filter that occur with temperature variations. In another embodiment, a collet assembly provides means for selectively compressing a filter chip to tune the filter response.
