Study on Characteristics of a Novel Waveguide Array Electro-optic Scanner
, , and
Effect of the mutual coupling among waveguides on propagating and scanning characteristics of waveguide array electro-optic scanner (WAEOS) is studied by use of the finite-difference beam-propagation method (FD-BPM). The results indicate that the mutual coupling is usually of great influence on these characteristics buEffect of the mutual coupling among waveguides on propagating and scanning characteristics of waveguide array electro-optic scanner (WAEOS) is studied by use of the finite-difference beam-propagation method (FD-BPM). The results indicate that the mutual coupling is usually of great influence on these characteristics but it is of little influence on them only under some certain conditions. Therefore, in order to design structure of WAEOS appropriately, it is necessary to consider the effect of the mutual coupling on propagating and scanning characteristics fully. Some parameters, which are used to describe performance of WAEOS, are put forward and then the optimal structure of WAEOS is discussed with considering the mutual coupling fully..

Compression-Factor-Controllable Optical Pulse Compressor
, , and
A compression-factor-controllable optical pulse compressor is proposed. This compressor consists of a comb-like dispersion-profiled fiber (CDPF) and a Raman amplifier. Sections of the dispersion shifted fibers and single mode fibers are used as the CDPF and Raman gain medium. Tunable compression factor is achieved by cA compression-factor-controllable optical pulse compressor is proposed. This compressor consists of a comb-like dispersion-profiled fiber (CDPF) and a Raman amplifier. Sections of the dispersion shifted fibers and single mode fibers are used as the CDPF and Raman gain medium. Tunable compression factor is achieved by controlling the pump power of the compressor for a given pulse train. The performance of the optical pulse compressor is demonstrated by a simulation method based on nonlinear Schrdinger equation. When propagating in the CDPF, optical pulse is compressed and amplified. The output pulse width could be tuned by controlling the power of Raman pump. A good linear relationship between the Raman pump power and the compression factor is achieved by optimizing the structure of the CDPF..

, , , and
Utilizing the entanglement property of Greenberger-Horne-Zeilinger (GHZ) state, a theoretical scheme to realize multicontrol remote single qubit unitary transformation is presented. In the present scheme, one party (Alice) can perform a unitary transformation on remote quantum system (Bob), in which the full structure Utilizing the entanglement property of Greenberger-Horne-Zeilinger (GHZ) state, a theoretical scheme to realize multicontrol remote single qubit unitary transformation is presented. In the present scheme, one party (Alice) can perform a unitary transformation on remote quantum system (Bob), in which the full structure of the unitary transformation is in a sense split and controlled locally by the two parties. By adjusting the measurement basis, the third (Cindy) can modulate the entanglement between Alice and Bob to control the probability of successful implementation. The communication between Cindy and Alice (Bob) is also controlled by Cindy in quantum way..
