摘要： A clock recovery system recovers an optical clock signal from an optical data signal that is wavelength and data rate independent. The system splits the optical data signal into a first optical data signal and a second optical data signal. The system then transmits the first optical data signal and the second optical data signal in opposite directions around a fiber loop. In the fiber loop, the system modulates and amplifies the first optical data signal to generate a modulated-amplified first optical data signal. The system then recovers the optical clock signal after the modulated-amplified first optical data signal and the second optical data signal interact in the fiber loop.

摘要： A method is provided for measuring polarization dependent loss in an optical transmission system. In the method, a first optical signal is generated, and a polarization of the first optical signal is altered over time. The first optical signal is combined with a second optical signal from the optical transmission system to yield a combined optical signal, which is coherently detected to yield a radio frequency signal. A power of the radio frequency signal is measured. The measured power of the radio frequency signal is processed to generate an indication of the polarization dependent loss of the optical transmission system.

摘要： In a WDM transmission system carrying amplitude modulated traffic in which significant cross-phase modulation occurs, each of the individual channels is pre-chirped at the transmitter with replicas, or low-pass filtered replicas of the amplitude modulation applied to each of the other channels. Prechirping of each individual channel with a replica of the amplitude modulation applied to that channel may be added in order additionally to provide compensation for self-phase modulation.

摘要： A mobile target screen is described for ball game practicing and simulation. Tow force sensors are mounted at each of the four corners of the frame which holds a target screen. Measurements form the force sensors are used to compute and display a representation of ball speed, the location of the ball on the target screen, and the direction of the ball motion. These parameters can be used to predict the shooting distance and the landing position of the ball. It also provides enough information to predict the trajectory of the ball which can be displayed on a video screen which communicates with the sensors through a wireless transceiver.

摘要： A compact source capable of generating continuously tunable high frequency microwave radiation and short optical pulses in the picosecond/sub-picosecond range is invented. It includes a laser structure having two lasers formed on the same substrate which simultaneously operate at different longitudinal modes. Each laser has a complex coupled (gain-coupled or loss-coupled) grating which is formed by deep etching through a multi-quantum well structure, either of the active medium or of the additional lossy quantum-well layers, thus ensuring no substantial interaction between lasers. The lasers have a common active medium and shared optical path and provide mutual light injection into each other which results in generation of a beat signal at a difference frequency of two lasers. The beat frequency is defined by spacing between the laser modes and may be continuously tuned by current injection and/or temperature variation. Thus, the beat signal provides a continuously tunable microwave radiation. To form a train of short optical pulses, the beat signal is either further sent to a saturable absorber followed by a semiconductor optical amplifier, or sent directly into an optical compressor which includes a dispersion fiber. As a result, a duration of each impulse is compressed, and a train of short optical pulses is formed.
