Abstract:
A radiation sensor device comprising a body portion having an entrance through which radiation may enter the body portion, a radiation detector and an optical filter interposed between the entrance and the radiation detector. The radiation detector is capable of detecting radiation having at least one wavelength in the range of from about 125 nm to about 1100 nm, and comprises: (i) a silicon-containing material comprising an n-doped layer disposed on a pair of p-doped layers, and (ii) a passivation layer disposed on a radiation impingement surface of the siliconcontaining material, the passivation layer comprising nitrided silicon dioxide, a metal silicide and mixtures thereof. The optical filter has: (i) an optical transmittance of at least about 40% at a wavelength in the range of from about 175 nm to about 300 nm, and (ii) an optical transmittance of no greater than about 5% at a wavelength greater than about 350 nm.
Abstract:
The present invention provides an optical system that includes an array of opto-electronic devices, an array of micro lenses, and a fore optic. The array of opto-electronic devices lie substantially along a plane, but the fore optic has a nonplanar focal field. To compensate for the non-planar focal field of the fore optic, each opto-electronic device has a corresponding micro lens. Each micro lens has a focal length and/or separation distance between it and it respective optoelectronic device, which compensates for the non-planar focal field of the fore optic. The focal lengths of these lenses may differ relative to one another. As a result, light that is provided by the fore optic is reconfigured by the micro lenses having various focal lengths to be substantially focused along the plane of the array of opto-electronic devices. Various arrangements of microlenses, placing lenses on standoffs or posts, forming of optical waveguides, lens fabrication, wafer integration of micro-optics, and optical coupling are noted.
Abstract:
A method for manufacturing a cover assembly including a transparent window portion and a frame that can be joined to a micro-device package base to form a hermetically sealed micro-device package. First, a frame is provided having a continuous sidewall defining a frame aperture therethrough. The sidewall includes a frame seal-ring area circumscribing the frame aperture. The frame seal-ring area has a metallic surface. A sheet of a transparent material is provided having a window portion defined thereupon. The window portion has finished top and bottom surfaces. Next, a sheet seal-ring area on the sheet is prepared, the sheet seal-ring area circumscribing the window portion. Next, the prepared sheet seal-ring area of the sheet is metallized. Next, the frame is positioned against the sheet such that at least a portion of the frame seal-ring area and at least a portion of the sheet seal-ring area contact one another along a continuous junction region that circumscribes the window portion. Next, the junction region is heated until a metal-to-metal joint is formed between the frame and sheet all along the junction region, whereby a hermetic seal circumscribing the window portion is formed.

A spectrally tunable optical detector and methods of manufacture therefore are provided. In one illustrative embodiment, the tunable optical detector includes a tunable bandpass filter, a detector and readout electronics, each supported by a different substrate. The substrates are secured relative to one another to form the spectrally tunable optical detector.
