摘要： A multiple wavelength light source generates an output signal having a comb of accurately spaced apart frequencies with variable free spectral range in the C-band of optical fiber communication. The light source employs an electro-optical modulator (EOM) driven by a signal generator which modulates with EOM with multiple modulation frequencies to widen the output spectrum of signal. The EOM has a crystal provided with a waveguide. The waveguide may be doped with a rare-earth metal to impart gain properties to equalize the intensities of the comb. In one preferred embodiment, Er, Yt or other doping elements provide the gain property to waveguides. The crystal is also provided with periodically poled structure, and this may be engineered so as to form domains of unequal widths to improve the efficiency of modulation. The output signal from the light source may be split and presented to a bank of filters to create a multiple signals, each signal having one of the spaced apart frequencies. The output signals may be used as channels to be modulated by data and then combined in dense wavelength division multiplexing system, or may be used as a soliton source in time-division multiplexed communication systems.

摘要： A photo-thermal, interferometric spectroscopy system is disclosed that provides information about a chemical at a remote location. A first light source assembly is included that emits a first beam. The first beam has one or more wavelengths that interact with the chemical and change a refractive index of the chemical. A second light source produces a second beam. The second beam interacts with the chemical resulting in a third beam with a phase change that corresponds with the change of the refractive index of the chemical. A detector system is positioned remote from the chemical to receive at least a portion of the third beam. The detector system provides information on a phase change in the third beam relative to the second beam that is indicative of at least one of, absorption spectrum and concentration of the chemical.

摘要： A system for high fidelity analog RF photonic communications is disclosed wherein linear phase modulation and linear coherent demodulation is included. A single optical beam with a phase-modulated signal optical carrier combined with an orthogonally polarized reference unmodulated optical carrier is transmitted simultaneously. At the receiver, the polarization of the reference carrier is transform to match that of the signal followed by coherent detection. An in-phase and quadrature-phase component of the homodyne signal is generated where they are digitized and processed to recover the original RF signal.

摘要： A method and system for high Z material revealing using muon detection technique is presented. The system measures muons' coordinates, velocities, incidence angles and leaving angles. Two series of detectors: one above and one below the interrogated volume are used. A muon trajectory deviation from an expected trajectory is used for the decision making on the presence of high Z material inside the volume. The muon velocity is measured using either a ring Cerenkov counter, a transition radiation detector or/and a threshold Cerenkov counter. The expected trajectory is calculated basing on known particle velocity.

摘要： A method and system for high Z substance revealing using muon detection technique is presented. Natural muon coordinate and incidence angle are measured above and below the interrogated volume. The muon deviations after passing through the interrogated volume are compared with the reference deviations obtained for the same volume in absence of high Z material. A correlation between the actual data and reference data is calculated using Kolmogorov-Smirnov test, though other approaches may apply. The correlation is used for the decision making on the presence of a nuclear substance inside the volume.
