Abstract: A device and a method for producing reaction plastics, including a first metering device with a first metering unit and a second metering unit, each of which is suitable for receiving and dispensing a first mixing component in a metered manner, a second metering device which is suitable for receiving and dispensing a second mixing component in a metered manner, and a mixing device which is suitable for receiving and mixing the first mixing component dispensed by the first metering unit and/or the second metering unit of the first metering device and the second mixing component dispensed by the second metering device.

Abstract: According to an aspect, an optical system includes a laser diode configured to emit optical signals and at least two size-switchable broken racetrack ring resonators optically coupled to an optical waveguide, where each broken racetrack ring resonator is configured to exhibit a resonant wavelength. The optical system also includes a tuning arrangement associated with the broken racetrack ring resonators, where the tuning arrangement includes a micro electro-mechanical system (MEMS) or nano electro-mechanical system (NEMS) actuator mechanically coupled to a first portion of a first one of the broken racetrack ring resonators and configured to mechanically move the first portion so as to change the resonant wavelength of the first one of the broken racetrack ring resonators.

Abstract: An electronic-photonic integrated-circuit assembly comprises a carrier substrate (310) and one or more integrated-circuit dies (330, 340) bonded to one another so as to form a die stack with exterior surfaces corresponding to an outer surface of a first one of the integrated-circuit dies and to an outer surface of a second one of the integrated-circuit dies, where at least one of the integrated-circuit dies includes one or more integrated photonic devices. One or more channels or passages (320) are formed into the outer surface of the first one of the integrated-circuit dies, and a first surface of the carrier substrate (310) is bonded to the outer surface of the first one of the integrated-circuit dies, thereby enclosing the one or more channels or passages (320), The integrated-circuit dies are electrically connected to each other via electrically conductive through-wafer interconnects or electrically conductive through-wafer vias.

Abstract: A device for forming a plastic component, which device has a body which is suitable for use in a device for producing a plastic component from a first compound, and which is formed in such a way that, when used in the device for producing plastic components, by being guided past the body, the first compound is brought into a form which has at least one cavity which is continuous in the direction of the guiding past. The device additionally has a line system arranged in the body, through which a second compound can be expelled from an end of the body, in order to introduce a second compound into the cavity while the first compound is guided past the body.
