摘要： A fiber laser for producing high energy ultrashort laser pulses, having a positive-dispersion fiber segment and a negative-dispersion fiber segment joined in series with the positive-dispersion fiber segment to form a laser cavity. With this configuration, soliton effects of laser pulse circulation in the cavity are suppressed and widths of laser pulses circulating in the cavity undergo large variations between a maximum laser pulse width and a minimum laser pulse width during one round trip through the cavity. The fiber laser also provides means for modelocking laser radiation in the laser cavity, means for providing laser radiation gain in the laser cavity, and means for extracting laser pulses from the laser cavity. Using selected positive- and negative-dispersion fiber segments, the laser cavity exhibits a net positive group velocity dispersion, and the ratio of the maximum laser pulse width to the minimum laser pulse width attained during one round trip through the cavity is greater than 5, and preferably greater than 10. The laser cavity may be configured as a linear cavity geometry, a ring cavity geometry, a figure eight geometry, or a Sagnac loop reflector geometry, among others. Preferably the ring cavity is configured to achieve unidirectional circulation of laser pulses in the ring cavity, and with this configuration, is shown to produce laser pulses having a pulse width of less than 100 fs and a pulse energy of at least 80 pJ.

摘要： An optical data signal can be sampled by linearly combining the optical data signal with optical sampling pulses, and delivering the combination to first and second balanced detectors. The optical data signal and the optical sampling pulse are configured to have a first phase difference at the first balanced detector and a second phase difference at the second balanced detector. Typically, a difference between the first phase difference and the second phase difference is configured to be about 90 degrees. In-phase and quadrature balanced detector outputs can be combined as a sum of squares to produce a linear sampling signal representative of data signal intensity, and the sample pulses can be configured to temporally step through the optical data signal so that a sampled representation of the optical data signal is obtained.

摘要： An N×N crossconnect switch is implemented without the use of waveguide crossings.

摘要： A thermo-optic device and a method for using it are described. The device has a substrate including a pair of waveguides coupled at first and second coupling regions. At the first coupling region, an input signal is split between the two waveguides. Between the coupling regions on one of the waveguides is a demultiplexer, at least one phase shifting device, and a multiplexer. The signal portions recombine at the second coupling region. Heater strips at the first and second coupling regions alter the temperature at the first and second coupling regions, in response to applied control signals, thereby adjusting the insertion loss and dynamic range of the device. A sensor samples an output signal from the substrate and sends a signal to a controller, which controls the phase shifting devices and the heater strip to maintain the output signal within predetermined signal parameters.

摘要： A multi-frequency optical signal source is adapted to include a plurality of power splitters, each connected to obtain a portion of an electrical data signal used to modulate a different one of the plurality of input optical sources; a plurality of delay means, each connected to an output of a different power splitter, each delay means providing a different predetermined signal delay; and an electrical signal combiner having a plurality of inputs, each input connected to a different output of the respective delay means, for electrically combining a portion of the modulation signal received from the connected delay means to form a combined electrical signal at an output of the electrical signal combiner, the output of the combiner being connected to control biasing of the optical output amplifier. The resulting multi-frequency optical signal source exhibits reduced signal distortion and crosstalk by keeping the carrier density constant in its shared optical output amplifier.
