Quantum Information Generation Using Optical Potential Well.

A molecular cryptography technique using optical tweezer, is presented. The modified add/drop filter system consisting of one centered ring and one smaller ring on the left side can be used to generate narrow pulse of tweezer. The optical tweezer transports the molecules in the communication network system. Tweezer generated by the dark-Gaussian behavior can be in the form of a potential well. The dark soliton propagates inside nonlinear microring resonator (NMRR) system, where the input Gaussian pulse control the output signal at the drop port of the system. Output optical tweezers can be connected to the quantum signal processing system consisting of a transmitter and a receiver. The transmitter is used to generate the high capacity quantum codes within the series of MRR's and an add/drop filter. The receiver will detect the encoded signals known as quantum bits. The transmitter will generate the entangled photon pair, propagating via an optical communication link. Here, optical tweezer with full width at half maximum (FWHM) of 13.08 and 12.63 nm are obtained at the drop and through ports of the system respectively. These results are in the form of potential well used to be transmitted through quantum signal processor via an optical fink. [ABSTRACT FROM AUTHOR]
