Abstract

Nonlinear, multicore, directional couplers exhibit power dependent transmission characteristics which have a wide range of potential applications in future all optical systems. These include modulators , power splitters , wavelength filters and all optical interconnections.[1] Recent theoretical studies [2] have shown that three guide couplers have sharper switching characteristics than the standard dual core coupler and should therefore, be of interest in all-optical switching , pulse narrowing and pulse shaping applications. In addition, multiguide structures with varying coupling coefficients have also been studied with a view to observing discrete spatial solitons [3] and have potential utilization in beam steering and switching applications.
