Transmission properties in waveguides: an optical streamline analysis.
We present a novel approach to study transmission through waveguides in terms of optical streamlines. This theoretical framework combines the computational performance of beam propagation methods with the possibility to monitor the passage of light through the guiding medium by means of these sampler paths. In this way, not only can the optical flow along the waveguide be followed in detail, bu...
متن کاملTransmission Properties of Two Shifted Magnetoinductive Waveguides
Transmission properties of magnetoinductive waves propagating in two coupled one-dimensional metamaterial arrays are studied both experimentally and theoretically for the case when one of the arrays is shifted relative to the other one. Two different kinds of resonant metamaterial elements, split-pipe and spiral resonators, are investigated in the frequency bands centred at 46.2 and 586 MHz, re...
متن کاملOptical limiting properties of nonlinear multimode waveguides.
An experimental investigation of the transmission of multimode capillary waveguides with a nonlinear absorber in the core shows an enhanced nonlinear absorption relative to the same length of bulk material. The results are consistent with partial mode filling within the cores of the waveguides. This study confirms the promising optical limiting capabilities of multimode nonlinear waveguides and...
متن کاملCoupled nanopillar waveguides: optical properties and applications
In this paper we review basic properties of coupled periodic and aperiodic nanopillar waveguides. A coupled nanopillar waveguide consists of several rows of periodically or aperiodically placed dielectric rods (pillars). In such a waveguide, light confinement is due to the total internal reflection, while guided modes dispersion is strongly affected by the waveguide structure. We present a syst...
متن کاملAnalysis of integrated optical waveguides
An overview of the analysis of integrated optical waveguides is presented. Starting from the Maxwell’s equations, a formulation of the problem for general 3-D structures will be introduced. Then, for longitudinally invariant structures, problem for waveguides with 2-D cross section is presented for vectorial, semivectorial, and scalar formulations. Simpler 1-D case for planar structure will the...
