摘要： An integrated semiconductor device is formed from two fabricated semiconductor devices each having a substrate by placing an etch-resist on the substrate of the one semiconductor device, by bonding the conductors of one of the fabricated semiconductor devices to the conductors of the other fabricated semiconductor device, flowing an uncured cement (e.g. epoxy) between the etch-resist and the other substrate, allowing the cement to solidify, and removing the substrate from the one of the semiconductor devices. More specifically, a hybrid semiconductor device is formed from a GaAs/AlGaAs multiple quantum well modulator having a substrate and an IC chip having a substrate by placing an etch resist on the modulator substrate, bonding the conductors of the modulator to the conductors of the chip, wicking an uncured epoxy between the modulators and the chip, allowing the epoxy to cure, and removing the substrate from the modulator.

摘要： A detector array for detecting an optical signal includes a plurality of pixels. Each pixel has a plurality of detector elements coupled together in a redundant configuration such that the detector array maintains a substantially uniform response even if each of the pixels includes a number of defective detector elements. The optical signal is lengthened in the direction normal to the information vector, so that each detector element is exposed to the same portion of the optical signal. A bad-element sensor is coupled to each detector element, which is functionally responsive to the detection of a bad detector element.

摘要： In an improved method for manufacturing an integrated composite semiconductor device according to the present invention, a semiconductor-based stop-etch layer having holes therein at selected sites is disposed over the epoxy or other flowable hardener used in flip-chip bonding. The hardener underneath the openings in the stop-etch layer is subtantially removed via a dry etch applied therethrough, exposing desired structure, such as bonding pads, formerly covered by the hardener. The epoxy underneath the stop-etch layer is substantially preserved.

摘要： A modulator having low insertion and a broad operating bandwidth is disclosed. The modulator has a movable membrane that is spaced from a substrate. The reflectivity of the movable membrane, and the reflectivity of the subtrate/gap interface are unequal. In particular, relative to the membrane, the substrate has a lower reflectivity. Device finesse is dictated by the lower reflectivity "mirror," i.e., the substrate. The substrate configuration thus provides a broad operating bandwidth while the higher reflectivity membrane provides low insertion loss.

摘要： A hybrid chip having at least two different types of semiconductor devices co-located on a common substrate, and a method therefor, are disclosed. The devices have different multiple epitaxial layer structures so that each different type of device is first grown on a separate appropriately-selected substrate, and then attached to the common substrate. According to the method, a first device is attached to the common substrate using flip-chip bonding methods. Flip-chip bonding involves attaching the device and the substrate at bonding pads, flowing a flowable hardener between the first device and the common substrate and allowing it to harden, and then removing the substrate upon which the first device was grown. The hardener is removed before attaching the second type of device via flip-chip bonding.

摘要： An optical filter for correcting non-linear gains across a wavelength band includes a first layer having a first layer thickness according to the formula: first layer thickness=m&lgr;/(4nfirst), where m is an odd multiple integer, &lgr; is the central wavelength of the wavelength band, and nfirst is the refractive index of the first layer, and a second layer having a second layer thickness according to the formula: second layer thickness=&lgr;/(4nsecond), where &lgr; is the central wavelength of the wavelength band, and nsecond is the refractive index of the second layer. The optical filter introduces an insertion loss for wavelengths in a wavelength band of optical fiber transmission having an insertion loss curve approximating a quadratic shape in the wavelength band and having a maximum insertion loss at a central wavelength of the wavelength band.

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.
