摘要

An optical universal shift register has been demonstrated based on the electro-optic effect of lithium niobate (LiNbO_3) in Mach-Zehnder interferometer (MZI), which can be used as a building block for optical computing and optical signal processing systems. The proposed device comprises of two serially connected optical D flip-flops and two multiplexers. Each optical D flip-flop consists out of three MZIs sharing a single clock pulse. The two cascaded multiplexers are controlled by the electric pulses in order to perform the bidirectional shifting and parallel loading operation of optical pulses. The pulse shifting behavior is analyzed using Beam propagation method and verified with the help of MATLAB simulations and function table.
