Title: Method and apparatus for optical phase error correction

Abstract

The phase value of a phase-sensitive optical device, which includes an optical transport region, is modified by laser processing. At least a portion of the optical transport region is exposed to a laser beam such that the phase value is changed from a first phase value to a second phase value, where the second phase value is different from the first phase value. The portion of the optical transport region that is exposed to the laser beam can be a surface of the optical transport region or a portion of the volume of the optical transport region. In an embodiment of the invention, the phase value of the optical device is corrected by laser processing. At least a portion of the optical transport region is exposed to a laser beam until the phase value of the optical device is within a specified tolerance of a target phase value.

  • Free-space optical (FSO) laser communication systems offer exceptionally wide-bandwidth, secure connections between platforms that cannot other wise be connected via physical means such as optical fiber or cable. However, FSO links are subject to strong channel fading due to atmospheric turbulence and beam pointing errors, limiting practical performance and reliability. We have developed a fade-tolerant architecture based on forward error correcting codes (FECs) combined with delayed, redundant, sub-channels. This redundancy is made feasible though dense wavelength division multiplexing (WDM) and/or high-order M-ary modulation. Experiments and simulations show that error-free communications is feasible even when faced with fades that are tensmore » of milliseconds long. We describe plans for practical implementation of a complete system operating at 2.5 Gbps.« less
  • The intensity and phase of one or more ultrashort light pulses are obtained using a non-linear optical medium. Information derived from the light pulses is also used to measure optical properties of materials. Various retrieval techniques are employed. Both "instantaneously" and "non-instantaneously" responding optical mediums may be used.
  • Schemes are described for generating tunable coherent radiation by noncollinear phase-matched sum-difference frequency optical mixing in a nonlinear medium for use, by way of illustration, in connection with /sup 235/U separation in UF/sub 6/.
  • The various technologies presented herein relate to correcting a time-dependent phase error generated as part of the formation of a radar waveform. A waveform can be pre-distorted to facilitate correction of an error induced into the waveform by a downstream operation/component in a radar system. For example, amplifier power droop effect can engender a time-dependent phase error in a waveform as part of a radar signal generating operation. The error can be quantified and an according complimentary distortion can be applied to the waveform to facilitate negation of the error during the subsequent processing of the waveform. A time domainmore » correction can be applied by a phase error correction look up table incorporated into a waveform phase generator.« less
  • A dielectric well logging system includes a logging tool adapted to be passed through a borehole traversing an earth formation. The logging tool includes a transmitter which induces electric energy into the earth formation at a radio frequency. Two receivers in the logging tool spaced a distance apart provides intermediate frequency signals corresponding to the electrical energy received from the earth formation. The intermediate frequency signals are transmitted by a cable to the surface. Surface electronics include zero crossing detectors, each detector receives a different intermediate frequency signal from the cable and provides a detector signal whose change in amplitudemore » is representative of the intermediate frequency signal passing through zero. A source provides clock pulses at a frequency greater than the frequency of the intermediate frequency signals. A logic circuit receiving the detector signals and the clock pulses provides clock pulses in accordance with the detector signals. The number of clock pulses in each group corresponds to the dielectric constant of the earth formation.« less
