摘要： Integrated circuitry is fabricated from semiconductor layers formed on a substrate, which include at least one n-type layer, an inverted p-type modulation doped quantum well (mod-doped QW) structure, a non-inverted n-type mod-doped QW structure, and at least one p-type layer including a first P+-type layer formed below a second P-type layer. An etch operation exposes the second p-type layer. P-type ions are implanted into the exposed second p-type layer. A gate electrode of a n-channel HFET device is formed in contact with the p-type ion implanted region. Source and drain electrodes of the n-channel HFET device are formed in contact with n-type ion implanted regions formed in contact with the n-type mod-doped QW structure. P-channel HFET devices, complementary BICFET devices, stacked complementary HFET devices and circuits and/or logic gates based thereon, and a variety of optoelectronic devices and optical devices can also be formed as part of the integrated circuitry.

摘要： Interference caused by the propagation of a transmit signal transmitted from a transmit antenna to a receive antenna is effectively cancelled by an improved signal cancellation system. The system includes an interference cancellation signal generator that generates a time-delayed and amplitude-reduced representation of said transmit signal. A summing stage is operably coupled to the interference cancellation signal generator and the receive antenna. The summing stage subtracts the time-delayed and amplitude-reduced representation of the transmit signal from a receive signal to substantially cancel the interference. The interference cancellation signal generator preferably includes a novel programmable optical delay line that introduces a variable amount of optical delay to an optical signal derived from said transmit signal in addition to a thyristor-based sigma delta modulator that converts samples of the transmit signal to into a digital signal in the optical domain.

摘要： A thyristor and family of high speed transistors and optoelectronic devices are obtained on a monolithic substrate (149) with an epitaxial layer structure comprised of two modulation doped transistor structures inverted with respect to each other. The transistor structures are obtained by adding planar doping to the Pseudomorphic High Electron Mobility Transistor (PHEMT) structure. For one transistor, two sheets of planar doping of the same polarity separated by a lightly doped layer are added which are opposite to the modulation doping of the PHEMT. The combination is separated from the PHEMT modulation doping by undoped material. The charge sheets are thin and highly doped. The top charge sheet (168) achieves low gate contact resistance and the bottom charge sheet (153) defines the capacitance of the field-effect transistor (FET) with respect to the modulation doping layer of the PHEMT For the other transistor, only one additional sheet is added.

摘要： A family of optical waveguide structures and high speed optoelectronic/transistor devices are obtained from a multilayer structure that includes a modulation doped quantum well structure formed over a DBR mirror. The optical waveguide structure is realized by implanting n-type ions to form a pair of n-type implant regions that define a waveguide region therebetween. An oxide layer (e.g., SiO2) is deposited over the waveguide region. A thermal annealing operation causes the oxide layer to introduce impurity free vacancy disordering that substantially eliminates absorption in the waveguide region. The waveguide region contributes to lateral confinement of light therein. An etching operation etches through the n-type implant regions to define sidewalls, which are subject to an oxidation operation that produces oxidized sections along the sidewalls. The oxide layer is removed, and a top distributed bragg reflector mirror is formed over the waveguide region. The resulting structure realizes an optical waveguide. Optoelectronic devices (including lasers, detectors, modulators, amplifiers) and transistor devices (including enhancement-mode and depletion mode JFET devices and bipolar-type devices) are also realized from the same multi-layer structure and share many of the fabrication steps of the optical waveguide, to thereby provide for efficient monolithic integration of a broad array of optical/optoelectronic/electronic devices.

摘要： An integrated circuit includes a heterojunction thyristor device having an anode terminal, a cathode terminal, a first injector terminal operably coupled to a first quantum well channel disposed between the anode terminal and the cathode terminal, and a second injector terminal operably coupled to a second quantum well channel disposed between the anode terminal and the cathode terminal. Bias elements operate the heterojunction thyristor device in a mode that provides substantially linear voltage gain for electrical signals supplied to at least one of the first and second injector terminals for output to at least one output node. Preferably, the bias elements include a first DC current source operably coupled to an n-type modulation doped quantum well structure, a second DC current source operably coupled to a p-type modulation doped quantum well structure, a first bias resistance operably coupled between a high voltage supply and the anode terminal, and a second bias resistance operably coupled between the cathode terminal and a low voltage supply. The bias elements provide a current passing from the anode terminal to the cathode terminal that is below a characteristic hold current for the heterojunction thyristor device to thereby inhibit switching of the heterojunction thyristor device. The DC current provided by the DC current sources controls the amount of voltage gain provided by the heterojunction thyristor device.

摘要： A semiconductor device includes a series of layers formed on a substrate, the layers including a first plurality of layers including an n-type ohmic contact layer, a p-type modulation doped quantum well structure, an n-type modulation doped quantum well structure, and a fourth plurality of layers including a p-type ohmic contact layer. Etch stop layers are used to form contacts to the n-type ohmic contact layer and contacts to the n-type modulation doped quantum well structure. Thin capping layers are also provided to protect certain layers from oxidation. Preferably, each such etch stop layer is made sufficiently thin to permit current tunneling therethrough during operation of optoelectronic/electronic devices realized from this structure (including heterojunction thyristor devices, n-channel HFET devices, p-channel HFET devices, p-type quantum-well-base bipolar transistor devices, and n-type quantum-well-base bipolar transistor devices).In another aspect of the present invention, a high performance bipolar transistor device is realized from this structure by implanting p-type ions in a interdigitization pattern that forms a plurality of p-type ion implant regions on both sides of the p-type modulation doped quantum well structure to a depth that penetrates the n-type ohmic contact layer. The interdigitization pattern of the p-type implants reduces capacitance between the p-type modulation doped quantum well structure and the n-type ohmic contact layer to enable higher frequency operation.

摘要： A edge emitting waveguide laser is obtained that derives its optical power from a vertical cavity laser structure. The vertical cavity laser with top and bottom Distributed Bragg Reflectors produces stimulated emission by resonance in the vertical direction but the optical power so generated is diffracted by a second order grating into an optical mode propagating in the optical waveguide formed by the upper and lower mirrors as cladding layers. The efficiency of the diffraction grating and the reflectivity of the mirrors are maximized so that essentially all of the light is coupled into the guide and the loss through the mirrors can be neglected. The same structure can be utilized as a detector, a modulator or an amplifier. The designated laser structure to achieve this form of operation is the inversion channel laser which is a laterally injected laser having both contacts on the top side of the device. Then the anode and cathode of the laser are essentially coplanar electrodes and the device is implemented in the form of a traveling wave laser, detector, modulator or amplifier which forms the basis for very high frequency performance.

摘要： A semiconductor device includes a substrate supporting a plurality of layers that include at least one modulation doped quantum well (QW) structure offset from a quantum dot in quantum well (QD-in-QW) structure. The modulation doped QW structure includes a charge sheet spaced from at least one QW by a spacer layer. The QD-in-QW structure has QDs embedded in one or more QWs. The QD-in-QW structure can include at least one template/emission substructure pair separated by a barrier layer, the template substructure having smaller size QDs than the emission substructure. A plurality of QD-in-QW structures can be provided to support the processing (emission, absorption, amplification) of electromagnetic radiation of different characteristic wavelengths (such as optical wavelengths in range from 1300 nm to 1550 nm). The device can realize an integrated circuit including a wide variety of devices that process electromagnetic radiation at a characteristic wavelength(s) supported by the QDs of the QD-in-QW structure(s). Other semiconductor devices are also described and claimed.
