摘要： Recent theoretical investigations have predicted the existence of axially frozen modes that arise when light is incident upon an anisotropic two-dimensional photonic crystal. Such electromagnetic modes are of interest since they suggest a near-zero group velocity with extraordinary amplitudes. The present invention addresses the crystal physics associated with realizing such effects and provides for the development of materials suitable for use in the forming photonic crystals that can exhibit such effects.

摘要： Double-sided, single-sided and ring electrode mesa resonators are provided that operate in the difficult 3 GHZ frequency with an electrode-free resonator area that serves as an energy-trapping area. The double-sided electrode-free resonator device is a double-sided mesa resonator plate, top and bottom wells, a mesa, and top and bottom electrodes deposited in such a way that the electrodes cover the plate surface and surround the mesa, which allows the mesa to protrude above the electrodes and provide an electrode-free resonator area. The top and bottom electrodes, which are acoustically coupled and controlled by acoustic gaps, create an electro-magnetic field and an excitation voltage within a vibrating area of the resonator plate generates an acoustic energy which is trapped within the resonator area and confined to the resonator area to minimize a leakage of the acoustic energy and provide a high Q factor at 3 GHz. The resonator has a resonator frequency determined by a resonator thickness dimension, t3, influences the resonator area's ability to function as an active element trapping the acoustic energy. The inventors herein have observed a strong relationship between decreased resonator thickness and motional impedance. Double-sided and single-sided filter devices based on the same principles are also provided.

摘要： A microcircuit package with an integrated acoustic isolator made up of a stacked acoustic filter. The package includes a rigid, electrically conductive housing with a IC module mounted therein. The acoustic filter includes two electroacoustic transducers mounted on opposite sides of a common wall of the package, one inside the package and the other outside. An a.c. power source is connected to the transducer that is mounted on the outside of the package. Electrical energy from the power source is converted by the outside transducer into acoustic energy which is conducted through the package wall to the inside transducer which reconverts the acoustic energy into electrical energy. The package wall has a significant thickness in comparison to the acoustic wavelength of the filter passband and is preferably equal to an integer number of one-half acoustic wavelengths. The transducer-wall combination acts as a filter having a passband tailored to prevent high-power microwave energy from being transmitted through the package wall.

摘要： An optic modulator having a transparent piezoelectric substrate, an active multiple quantum well (MQW) epilayer with bottom electrical contacts bonded to the substrate, wherein the substrate is cut such that its thermal expansion coefficient is matched or roughly matched to that of the MQW epilayer in the direction parallel to the long axes of the bottom contacts and so that the piezoelectrically-active direction of the substrate is normal to the long axes of the bottom contacts. In order to control the bias of the MQW epilayer a transparent contact is disposed over the MQW epilayer. In operation, the piezoelectric substrate, when activated, will displace an anisotropic strain on the MQW epilayer which will break the rotational symmetry in the plane of the MQW. This will result in anisotropic mixing of the heavy and light holes in the MQW epilayer and thus, will result in an anisotropic excitonic absorption of light normal to the MQW epilayer.

摘要： A method and apparatus for the contactless, non-destructive measurement of Hall coefficient and resistivity of a piezoelectric semiconductor sample. The material to be tested is formed in a disk which is supported at its edge by a holder. The disc is free to vibrate. Two pairs of electrodes, placed above and below the sample, excite the sample into and beyond piezoelectric resonance. Then a magnetic field is applied to the sample and the sample again driven into and beyond resonance. Comparison between the performance of the disk before and after application of the magnetic field yields data from which Hall coefficient can be determined.

摘要： A method and means for producing a zero temperature coefficient for providing frequency stabilization as well as adjusting the frequency at a particular temperature of a dielectric resonator comprised of a cylindrical dielectric resonator element mounted on a substrate and having a dielectric disc affixed to the top of the resonator element. A zero temperature coefficient is obtained by selectively choosing the thickness of the dielectric disc depending upon the temperature coefficients of the constituent material of both the disc and resonator element. The operating frequency at a given temperature is furthermore adjusted by including two mutually contiguous patterns of metallization on the top surface of the resonator element and the bottom surface of the dielectric disc and thereafter rotating the disc so that a predetermined percentage of overlap between the two patterns exists.

摘要： An acceleration resistant crystal resonator is made from a single quartz te that is optically twinned into a left-handed (LH) quartz portion and a right-handed (RH) quartz portion. According to the method, the optically twinned single quartz plate is formed into a resonator plate wherein the effective thickness of the (LH) portion is substantially the same as the effective thickness of the (RH) portion. The resonator plate is then mounted and bonded to the support structure of a crystal resonator enclosure. A pair of electrodes is then deposited onto the (LH) portion and a pair of electrodes deposited onto the (RH) portion. The thickness of the two pairs of electrodes is then adjusted so that the resonant frequency of the resonator on the (LH) portion is substantially the same as the resonant frequency of the resonator on the (RH) portion. The pairs of electrodes are then interconnected to each other and to an oscillator circuit so that in-phase vibration of the two portions is assured. The enclosure is then hermetically sealed.

摘要： An Interdigital Bulk Acoustic-Wave Transducer (IBAT) device is provided with pairs of exciting electrode fingers disposed sufficiently close together on the piezoelectric substrate and dielectric coating over the exciting electrode fingers to generate an IC-compatible voltage at relatively high electric field strength, resulting in a reduced region of excitation and uniform electric field strength distribution. The IBAT advantageously produces a lateral electric field substantially uniform over a substantial portion of the active BAW structure area, reducing, or virtually eliminating sharp voltage spikes, an electrical field produced by the low voltages resident on integrated circuit (IC) chips, usually of a magnitude of 10 volts, or lower, the planar electrode structure being compatible with IC processing techniques, such as photolithography and the BAWs produced thereby being essentially plane waves, with propagation away from, but with phase progression substantially parallel to, the substrate surface. Numerous IBAT structural arrangements are possible by advantageously over-coating the IBAT electrode finger stripes with an insulating dielectric in different configurations, and any possible configuration achieved through over-coating is considered to be within the contemplation of the devices and methods of the present invention. Interdigital bulk acoustic wave transducers and methods for exciting bulk acoustic waves with interdigital electrode fingers are also provided.
