摘要： A wavelength demultiplexer having at least two pairs of photodetectors is disclosed. The photodetectors are arranged in sequential layers along an optical path and the pairs of photodetectors are separated by a non-optically active insulator interposed between the pairs. The photodetectors differ in bandgap, and are arranged so that the optical signal passes through relatively larger bandgap photodetectors before being received by relatively smaller bandgap detectors. Each photodetector absorbs photons within a predetermined energy range and generates a voltage as a function of the absorbed energy. The photodetectors can be used to detect, and hence demultiplex, a wavelength-division-multiplexed signal.

摘要： A micromechanical optical modulator having a linear response in reflectivity, as a function of applied bias, and a method of operating and making same, are disclosed. The modulator consists of a movable layer suspended over a substrate. A gap is defined between the movable layer and the substrate. As the movable layer moves, the gap changes size, resulting in a change in modulator reflectivity. In operation, the movable layer moves within a linear operating regime under the action of an applied voltage, which is the sum of a constant bias and a signal from an analog source. A substantially linear operating characteristic, i.e., reflectivity versus applied voltage is obtained within the linear operating regime by properly selecting the size of the gap in the absence of the applied voltage and the range in the applied voltage.

摘要： A method and apparatus for a micromechanical modulator having a reduced-mass multilayer membrane is disclosed. The modulator includes a movable composite membrane suspended over a subtrate. The composite membrane consists of an overlayer and an underlayer. The overlayer is characterized by a thickness that is less than one-quarter of a wavelength of the optical signal being modulated. Under the action of a bias voltage, the movable membrane moves from a quiescent position to a second position closer to the substrate. The modulator is fabricated so that in either the quiescent position or the second position the gap between the composite membrane and the substrate is equal to d=m.lambda./4-n.sub.s s when n.sub.u is about equal to (n.sub.s) .sup.0.5, where m is an even integer, .lambda. is the wavelength of the optical signal being modulated, n.sub.s is the refractive index of the subtrate, n.sub.u is the refractive index of the underlayer, n.sub.o is the refractive index of the overlayer, and s is the thickness of the overlayer. More generally, the gap may be given by d=m.lambda./4-n.sub.s s+(n.sub.u -n.sub.s.sup.0.5) (.lambda./10) sin (4.pi.n.sub.o s/.lambda.).

摘要： An integrated semiconductor device is formed by bonding the conductors of one fabricated semiconductor device having a substrate to the conductors on another fabricated semiconductor device having a substrate, flowing an etch-resist in the form of a photoresist between the devices, allowing the etch-resist to dry, and removing the substrate from one of the semiconductor devices. Preferably the etch-resist is retained to impart mechanical strength to the device. More specifically, a hybrid semiconductor device is formed by bonding the conductors of one or more GaAs/AlGaAs multiple quantum well modulators to conductors on an IC chip, flowing a photoresist between the modulators and the chip, allowing the photoresist to dry, and removing the substrate from the modulator.

摘要： Each microminiature contact pad included in a dense array of pads on an electronic component contains a relatively thick layer of solder. The layer is treated to form a relatively thin brittle protective layer on the surface of the solder. The structure is then brought into contact with a contact pad in a mating array of pads on another component in a thermo-compression bonding step carried out below the melting point of the solder. In that step, the brittle layer is fractured. As a result, solid-state diffusion of conductive material occurs through fissures in the fractured layer, thereby to provide an electrical connection between mating pads on the two components.
