We report preliminary results on the development of compact (length < 100 microm) fiber-coupled dielectric-loaded plasmonic waveguide components, including Mach-Zehnder interferometers (MZIs), waveguide-ring resonators (WRRs) and directional couplers (DCs), whose operation at telecom wavelengths is controlled via the thermo-optic effect by electrically heating the gold stripes of dielectric-loa...

This paper explores the merits of the single-path selective-broadcast interconnection (SBI) implemented in fiberoptic technology. This is a static, passive, fiber-optic interconnection among a set of stations, each equipped with multiple, say r , transmitters and receivers. It employs c 2 buses, each interconnecting a subset of the stations, and provides a single optical path between any two st...

Coupled nonlinear Schrödinger (CNLS) equations for the fiber couplers with asymmetric selfphase modulation (SPM) and cross-phase modulation (XPM) are studied. With symbolic computation, oneand two-soliton solutions are obtained for the constantand variable-coefficient CNLS equations. Switching dynamics of the solitons is discussed, and effects of the second-order group-velocity dispersion β2, S...

The single-star optical network is limited in size b y the available power budget. When the network size exceeds the number of connections a star coupler can support, it becomes necessary to use multiple passive star couplers to implement the network. The cost of a multi-star optical network is determined by the number of fiber connections per station and the number of star couplers in the netw...

We report the results of our study on the role of microfluidic infiltration technique in improving the coupling characteristics of dual-core photonic crystal fiber (PCF) couplers. Using the finite element method (FEM), we evaluate the effective mode area, dispersion and coupling parameters of an infiltrated dual-core PCF. We use these parameters to design a compact and reconfigurable coupler by...

The nonlinear fiber coupler is considered as a Hamiltonian dynamical system with an infinite number of degrees of freedom, with the soliton states of the coupler being the singular points of this dynamical system. Numerical simulations show that arbitrary initial conditions give rise, asymptotically, to oscillations around some of the stable singular points and some amount of radiation. Example...
