Abstract :
Light propagation in a 2-D array of coupled optical cavities with Kerr nonlinearity driven by a plane holding beam is numerically studied. Optical bistability together with its modulational instability (MI) are investigated, and 2-D discrete cavity solitons are simulated. These simulations revealed the switching on/off of the solitons along with the ability of a proper Gaussian beam (GB) to control their positions. Soliton-soliton and soliton-GB interactions are considered, and finally, all-optical NOR , XNOR, and NAND gates are proposed as realized by this device.
