摘要： A digital optical receiver and clock recovery circuit for use in detecting and retiming optical data transmitted at rates up to and exceeding 40 Gb/s. The receiver is made, in part, of superconducting Josephson junctions. The receiver includes an optical signal detector, an SFQ (single flux quantum) transition detector for converting the signal from the photodetector into a stream of single flux quantum signals, and a clock recovery circuit. The clock recovery circuit includes a superconducting ring oscillator in which an SFQ pulse rotates and provides a clock signal at an output of the oscillator. When a pulse from the stream of single flux quantum pulses arrives from the transition detector, two pulses are generated in the ring oscillator. One of the pulses eliminates the rotating SFQ pulse and the second pulse replaces the rotating SFQ pulse, thereby recovering the phase of the clock signal in one bit.

摘要： A resonant coil for nuclear magnetic spectroscopy and microscopy and a method of making the coil are provided. The coil is in the form of nested, interrupted loops of a conductive material forming a distributed inductive element and having a plurality of capacitive elements with capacitance distributed over the periphery of the loops. The coil is preferably formed as a thin film of a superconductive material on an electrically nonconductive substrate. In one aspect of the invention, the current density in the coil is kept constant by providing an inductive element and a set of tapered, interidigitated capacitors having a uniform gap therebetween. The invention maximizes the current-carrying capacity of the coil. The invention further provides a method of making the coil by patterning a film of a conductive material on a substrat into a coil having a lower resonant frequency than the desired frequency of the final coil, placing the coil in an apparatus where it is exposed to increasing current, preferably within a magnetic field such as will be used during operation and finally trimming the coil to the desired resonant frequency trimmed by removal of part of the capacitive element of the coil.

摘要： A freestanding YBa2Cu3O7- delta or ferroelectric air bridge is disclosed. This structure is useful for membrane detectors and can be extended to applications in which the presence of a substrate can degrade electronic, thermal, and optical properties of the superconductor or ferroelectric structure. The air bridge is fabricated using conventional photolithography, ion-beam dry etching, and selective wet etching. In the preferred embodiment, a sacrificial dielectric layer is deposited between a supportive substrate and a layer of superconducting material. The dielectric layer is later etched away in selected regions to form the air bridge. Step coverage of epitaxial bridge layers has been achieved without significant degradation of the superconducting properties of YBa2Cu3O7- delta layers. Alternatively, YBa2Cu3O7- delta can be used as the sacrificial layer when a ferroelectric such as Pb(Zr,Ti)O3 is the desired air bridge material.

摘要： A system and method are disclosed, the system and method being designed for adaptively controlling multiple parameters within an RF telecommunications system to address the problem of interference while maximizing coverage and capacity. In one embodiment of the invention, there is provided a variable gain stage comprising an RF filter (20), amplifier (21) and a controller (23) responsive to a plurality of system parameters, on the base station receiver prior to or in place of the system RF front end. The system parameters of interest can include dynamic parameters such as received signal strength indication, idle channel disturbance, bit error rate, frame error rate and SINAD (signal-plus-noise-plus-distortion). The algorithm used to determine optimum gain at the receiver can also take into account a model of the traffic and dropped call rates as a function of time of day or day of week, adjacent cell site traffic and the like. In another embodiment of the invention, a variety of system parameters are measured and used to determine the optimum gain on the base station transmitter-side amplifiers. In yet another embodiment of the invention, the duration, power and frequency of interfering signals are dynamically sampled and the parameters used to adjust the filter characteristics of the base station receiver front-end filters.

摘要： An inter-resonator coupling scheme for a filter is disclosed. An interresonator coupling member is located between successive resonators in the filter. By adjusting the length and/or the proximity of the inter-resonator coupling member relative to the adjacent resonators, the ratio of energy transferred from resonator to resonator (via the inter-resonator coupling member) may be increased and/or decreased. By increasing the ratio of energy transferred from resonator to resonator, the bandwidth of the filter is increased and is made relatively insensitive to tuning which may occur via manipulation of field disturbances introduced by tuning tips. The inter-resonator coupling member is made of a conductive or superconductive material and contains at least three sections. The first section runs substantially parallel to an edge of the first resonator that is not profoundly influenced by the source of field disturbance. The third section runs substantially parallel to an edge of the second resonator that is not profoundly influenced by the source of field disturbance. A second section connects the first and third sections.
