    摘要: A light barrier comprising a semiconductor component (1) and to a method for detecting objects with a carrier (2), a semiconductor chip (4) which detects an electromagnetic radiation, a semiconductor chip (4) which emits an electromagnetic radiation, and a direction-selective element (5, 8), which delimits an angle range of the radiation which can be received by the detecting semiconductor chip (4) and/or of the radiation to be emitted by the emitting semiconductor chip (3), wherein a main radiation axis (V) of the radiation which can be received is tilted relative to a main radiation axis (U) of the radiation to be emitted.

    摘要: A photodetector includes a substrate and a layer of Ge formed on the substrate. A plurality of n-type doped regions and a plurality of p-type doped regions are formed in Ge region. These doped regions formed an alternating pattern. Electrodes are formed on n-type doped regions and on the p-type doped regions. The utilization of transparent electrodes increases the sensitivity of the photodetector without impacting speed.

    摘要: An optical waveguide structure includes an air-via region that receives an optical signal from an optical source. A photonic crystal cladding region is formed on the surface of the air-via region. The photonic crystal cladding region confines the optical signal within the air-via region and propagates the optical signal along the axial direction while ensuring near complete transmission of the optical signal.
