    摘要: A device for detecting polarization of light comprising a first photodetector tuned to absorb TE polarization, a second photodetector tuned to absorb TM polarization, and a circuit for comparing an output from the first and second photodetector for generating a polarization output. The first photodetector comprises a first reflector, an absorption layer on top of the first reflector, and a second reflector on top of the absorption layer. The second photodetector comprises a third reflector on top of an absorption layer, and a fourth reflector disposed under absorption layer.

    摘要: A silicon wafer having a distributed Bragg reflector buried within it. The buried reflector provides a high efficiency, readily and accurately manufactured reflector with a body of silicon. A photodetector using the buried layer to form a resonant cavity enhancement of the silicon's basic quantum efficiencies and selectivity is provided. The DBR is created by bonding of two or more substrates together at a silicon oxide interface or an oxide-oxide interface. In the former, an hydrogen implant is used to cleave silicon just above the bond line. In the latter, the bonding is at the oxide layers.

    摘要: A system for interferometrically detecting the present of bound material using a wave propagating waveguide and the influence on propagation time of bound material in the proximity of the waveguide. The waveguide layer thickness and the radiation wavelength λ are selected so that the effects on phase difference between the two radiations applied in the beam are minimal in the region directly adjacent the surface of the waveguide, so as to unmask the influence of the more distant bound materials.
