Implementation of a quantum phase gate by the optical Kerr effect
We show that the optical Kerr effect can be used to construct a quantum phase gate. It is well known from quantum nondemolition techniques that, as two photon field modes pass through a Kerr medium, the phase of each mode will be shifted, and the size of the phase shift will depend on the number of photons in both modes. We discuss the Hamiltonian responsible for this effect and show how this c...

This paper deals with the design and simulation of all-optical 4×2 encoderusing the wave interference effect in photonic crystals. By producing 4 opticalwaveguides as input and two waveguides as output, the given structure was designed.The size of the designed structure is 133.9 μm2. The given all-optical encoder has acontrast ratio of 13.2 dB, the response time of 0.45 ...
متن کاملUltra-Fast All-Optical Half Subtractor Based on Photonic Crystal Ring Resonators
Abstract: In this paper, we aim to design and propose a novel structure for all-opticalhalf subtractor based on the photonic crystal. The structure includes two optical switches,one power splitter, and one power combiner. The optical switches are made of theresonant rings which use the nonlinear rods for dropping operation. The footprint of thedesigned structure is about...
متن کاملAll-optical phase modulation effect in InGaAs/AlAsSb quantum well and its application to ultra-fast all- optical signal processing
Ultrafast all-optical cross phase modulation (XPM) effect in InGaAs/AlAsSb quantum well is reviewed and its application to ultrafast all-signal processing is presented. Error free demultiplexing operation from 160-Gb/s to 40-Gb/s with low gating power is demonstrated. Keywords; ultrafast signal processing; quantum well; cross phase modulation; 160-Gb/s
متن کاملRealization of an all-optical zero to pi cross-phase modulation jump.
We report on the experimental demonstration of an all-optical pi cross-phase modulation jump. By performing a preselection, an optically induced unitary transformation, and then a postselection on the polarization degree of freedom, the phase of the output beam acquires either a zero or pi phase shift (with no other possible values). The postselection results in optical loss in the output beam....
