摘要： A biochemical assay device optically scans individual biological sample containing wells in an assay plate. The device includes an imaging system overlaying the assay plate wherein a scanning light propagates by total internal reflection within an optical waveguide. The waveguide includes a plurality of pixel locations, each aligned with a well in the assay plate, at which total internal reflection is selectively frustrated to output an incident beam of light. That light illuminates the well and causes generation of an emission beam of light that is detected by a photoreceptor. The device further includes a driver circuit that controls the selective frustration of total internal reflection at each pixel location in order to scan each well in the assay plate. A processor is also included in the device to process the detected emission beams of light generated by the scanned wells for purposes of assaying the biological sample contained in each scanned well.

摘要： The present invention is directed to a micromirror optical multiplexer for directing light to an array of sensors. The micromirror optical multiplexer directs light from one or more sources onto multiple, coplanar sensors for the purpose of exciting fluorescence. The micromirror optical multiplexer includes at least one light source and a micromirror array having a top face and up to four side faces. Pivotable mirrors of the micromirror array are arranged in a multiple row, multiple column format on the top face. In addition, each of the side faces of the micromirror array has at least one row of pivotable mirrors. By pivoting one side face mirror and one top face mirror, a light source entering at one corner of the micromirror array can be directed to exit near normal incidence anywhere on the bottom of the device.

A CMOS fabricated photodetector array including a plurality of individual photoreceptors is selectively etched back between photoreceptor locations to reveal a plurality of recessed regions having a certain geographic profile. A plurality of semiconductor blocks, each having light emitting capability and each having a certain geometric profile that is complementary in size and shape to the certain geometric profile of the recessed regions, are separately fabricated.

The slurry is then flowed over the CMOS fabricated photodetector array in accordance with a fluidic self-assembly technique, and the included semiconductor blocks are individually deposited within each of the plurality of recessed regions in the CMOS fabricated photodetector array. The deposited blocks are then attached within the recessed regions to form the optical excitation/detection device from an arrayed plurality of photodetectors and separately formed photoemitters.

摘要： A laser system capable of providing light of high intensity is disclosed. This system includes a laser gain medium and three reflectors. A first reflector and a second reflector spaced from the first reflector define a laser cavity that contains the laser gain medium. The second reflector has a reflectivity (R.sub.2) larger than the reflectivity (R.sub.1) of the first reflector such that light emitted from the laser gain medium resonates in the laser cavity. A third reflector having a reflectivity (R.sub.3) larger than the reflectivity of the first reflector (R.sub.1) is spaced from the second reflector to define a resonant cavity external to the laser cavity. Light passes from the laser cavity to resonate in the external resonant cavity. Part of the light passes from the external resonant cavity to the laser cavity to optically lock the laser gain medium.

摘要： A laser system capable of providing light of high intensity is disclosed. This system includes a laser gain medium and three reflectors. A first reflector and a second reflector spaced from the first reflector define a laser cavity that contains the laser gain medium. Light reflected by the first reflector is amplified by the laser gain medium. A third reflector is spaced from the second reflector to define a resonant cavity external to the laser cavity. Light passes from the laser cavity to resonate in the external resonant cavity. Part of the light passes from the external resonant cavity to the laser cavity. A light-screening device, e.g., an aperture, is disposed between the second reflector and the gain medium to screen light reflected from the external cavity such that the light portion of constructive interference is preferentially passed over the light portion of destructive interference. This enables the gain medium to optically lock to the resonant frequency of the external cavity.
