Compact low loss and broadband hybrid plasmonic directional coupler.
We propose a novel broadband coupler for silicon photonics using a hybrid plasmonic waveguide section. The hybrid plasmonic waveguide is used to create an asymmetric section in the middle of a silicon nanowire waveguide coupler to introduce a phase delay to allow for a 3-dB power coupling ratio over a 150 nm bandwidth around 1.55 µm. The device is very compact (<8.5 µm) and has a low insertion ...
متن کاملUltra-Compact Directional Coupler Using Hybrid Plasmonic Waveguide with Dual Metallic Layers
We analyze hybrid plasmonic waveguides with metallic layers on two sides. Confinement of closely stacked metal induces large difference of effective indices of vertical even and odd modes. This phenomenon can be utilized as ultracompact vertical directional coupler. Simulation shows directional coupling can be achieved in less than 1 μm.
متن کاملDesign and Simulation of a Metal-Insulator-Metal Filter Based on Plasmonic Split Ring
In this paper, a plasmonic filter made of a split ring, two U-shaped structures and two straight waveguides is designed and investigated. In the proposed structure, the split ring and U-shaped structures are situated between straight waveguides. Simulations are done based on FDTD method. Split ring, U-shaped structures and straight waveguides are made of air in the silver background. In the pro...
متن کاملPolarization-independent hybrid plasmonic coupler for a silicon on insulator platform.
Hybrid plasmonic waveguides consisting of a high-index slab separated from a metal plane by a low-index spacer provide an optimal compromise between the loss and confinement for surface plasmon waves in passive medium. In such hybrid structures, because power for the TE and TM modes are concentrated in two different regions of the guide, the characteristics of the two modes can be controlled in...
متن کاملDesign of a Compact X-Band Substrate Integrated Waveguide Directional Coupler
Abstract— This paper presented the design of four-port network directional coupler at X-band frequency (8.2-12.4 GHz) by using substrate integrated waveguide (SIW) technique. SIW appears few years back which provides an excellent platform in order to design millimeter-wave circuits such as filter, antenna, resonator, coupler and power divider. It offers great compensation for smaller size and c...
