摘要： A retroreflector includes an arrangement of triples, each having three side surfaces, which are disposed in the manner of a cube corner and stand approximately perpendicular on one another. The retroreflector can be produced from a carrier material by injection molding. An optical silicone resin is used as the carrier material. The retroreflector is based on triple mirrors that are both easily unmolded from a die and easily applied to curved surfaces even after unmolding or are usable for reflection of ultraviolet light.

摘要： A silicon-on-insulator (SOI) substrate includes a silicon dioxide layer and a silicon layer. A detection region receives a detected optical mode coupled to an incident optical mode defined by an optical waveguide in the silicon layer. The detection region consists essentially of an intrinsic semiconductor material with a spacing structure surrounding at least a portion of the detection region, which comprises p-type, n-type doped semiconductor regions adjacent to first, second portions, respectively, of the detection region. A dielectric layer is deposited over at least a portion of the spacing structure. The silicon layer is located between the dielectric layer and the silicon dioxide layer. First, second metal contact structures are formed within trenches in the dielectric layer electrically coupling to the p-type, n-type doped semiconductor regions, respectively, without contacting any of the intrinsic semiconductor material of the detection region.

摘要： An optical sensor and filter assembly is provided and includes an optical sensor, a filter and a mounting structure. The optical sensor includes a detector layer having first and second opposed faces and a read-out integrated circuit (ROIC) to which the first face of the detector layer is hybridized. The filter permits passage of one or more wavelength bands of interest of incident light toward the optical sensor and the mounting structure directly hybridizes the filter to the second face of the detector layer.

摘要： The present application relates to an all-optical detector and detection system, a response time test system, and a manufacturing method. The all-optical detector comprises a micro-nanofiber and an optical resonant cavity. The micro-nanofiber comprises transition regions and a uniform region. The uniform region is connected to the transition regions. The optical resonant cavity is provided in the uniform region. The optical resonant cavity is made of a semiconductor material. The all-optical detector provided in the present application detects light by means of the change of a resonance peak, achieves all-optical detection, and has a high signal-to-noise ratio.

摘要： A lens plate (10) for a rain and/or light sensor is proposed. The lens plate (10) has a base body (18), at least one light limitation structure (21), and at least one lens structure (28), the light limitation structure (21) extending into the base body (18) from a lower side (14) of the lens plate (10), a contour (27) of the light limitation structure (21) facing away from the lower side (14) of the lens plate (10) limiting the lens structure (28) circumferentially, and the contour (27) being substantially triangular. Furthermore, a rain and/or light sensor (8) is proposed.

摘要： The invention relates to a single photon detector device for detecting an optical signal comprising an optical fiber and at least one nanowire, wherein the optical fiber comprises a core area and a cladding area and is designed to conduct the optical signal along an optical axis, wherein, with respect to the optical axis, a first area of the optical fiber is an entrance area for the optical signal and a second area of the optical fiber is a detector area, and wherein the nanowire becomes superconducting at a predetermined temperature and is designed in the superconducting state to generate an output signal as a function of the optical signal. It is provided that in the detector area of the optical fiber the nanowire extends essentially along the optical axis of the optical fiber. A single photon detector device is thus provided which has a simple structure, a high efficiency, a high detection rate and a high spectral bandwidth.
