Abstract:
An optical-microwave-quantum transducer can include a tapered optical fiber configured to transmit and receive optical signals. The optical-microwave-quantum transducer can also include a cantilever that can include an optical cavity that includes a nanophotonic crystal. The optical cavity can be configured to provide mechanical excitation in response to electromagnetic excitation induced by photons emitted from the tapered optical fiber. The cantilever can also include a mechanical coupler that is configured to induce electrical modulation onto a superconducting cavity in response to the mechanical excitation. The mechanical coupler can also be configured to provide mechanical excitation in response to electromagnetic excitation induced by photons from the superconducting cavity. The optical cavity can further be configured to provide electromagnetic excitation that induces optical modulation on the tapered optical fiber in response to the mechanical excitation.

Abstract:
Sensor comprising a detection element which outputs electrical signals, which sensor has superficial aluminium or aluminium-containing components, a first layer made of silicates being present on the surface of said components and a second layer, composed of n-octadecyltrichlorosilane, being applied to said first layer. Applicable to products such as gas sensors whose useful signals are very small, with the result that they are to be read out by means of field effect transistors. In these areas of signal processing, interference signals have to be precluded as far as possible. The product is a so-called GAsFET.
Abstract:
The invention concerns a nanowire structural element suited for use in a microreactor system or microcatalyzer system. A template based process is used for the production of the nanowire structural element, wherein the nanowires are electrochemically depositioned in the nanopores. The irradiation is carried out at different angles, such that a nanowire network is formed. The hollow chamber-like structure in the nanowire network is established through the dissolving of the template foil and removal of the dissolved template material. The interconnecting of the nanowires provides stability to the nanowire structural element and an electrical connection between the nanowires is created thereby.

Abstract:
The invention relates to a process for fabricating a monocrystalline silicon micromechanical element integrated with a CMOS circuit element within the CMOS technology. A portion of the surface layer of a monocrystalline substrate is selectively doped and a CMOS circuit element is fabricated within the substrate through the known steps of CMOS technology. Then, parts of the substrate underlying the selectively doped portion are etched porous through an exposed portion of the surface. Thereby, a buried sacrificial layer is formed. As a next step, metallic contact pieces of the circuit element through the known steps of CMOS technology are formed. Finally, the micromechanical element is formed by chemically dissolving said porous Si sacrificial layer.

The invention concerns a micromechanical sensor and a method for the production thereof. According to the invention, the diaphragm can be reliably mounted regardless of process-related vibrations of the cavern etching process and the diaphragm can be provided in any shape due to the fact that a suitable binding of the diaphragm in an oxide layer produced by local oxidation is formed.
