The nanoantenna coupler provides a compact interface between an optical fiber and a plasmonic slot waveguide for future optical integrated circuits. View Show abstract. The proposed vertical coupler shows more efficient light coupling between a dielectric and plasmonic waveguide in comparison to the other types of hybrid coupler. demonstration of ultra-compact directional couplers based on silicon hybrid plasmonic waveguides,” Appl. Phys. Lett., vol. , no. 24, pp. –, [7] Y.-P. Chiou and C.-H. Du, “Arbitrary-order full-vectorial interface condi-tions and higher-order finite-difference analysis of optical waveguides,”. Composite metal-dielectric-metal (MDM) surface plasmon polariton (SPP) structures are first proposed to realize the ultra-short optical splitters with simplified designs. The operation mechanism is based on the contra-directional coupling achieved in composite plasmonic slot waveguides. In certain cases, the switching function can also be realized.

At optical frequency, corresponding coupling length is just μm, this is an extremely small coupling length than previously reported by others. With modification in symmetric directional couplers designs and by providing a slow-light region, maximum normalized output waveguide power has been obtained equal to μw at s = by: 1. Principle. The schematic of the proposed graphene-plasmon hybrid photodetector is shown in Figure 1A, where the light from a fiber is first coupled to a silicon waveguide through a grating coupler [] and further to the plasmonic slot waveguide by a short tapered structure [], [].The plasmonic slot waveguide (see the cross-section of the device in Figure 1C) consists of two Author: Yunhong Ding.   Ultrafast optical control of plasmon provides a potential route towards novel high-speed active photonic devices 1,2,3,4,5,6,7,8,9,10,11,For this reason, considerable efforts have been devoted Cited by: Here, we report a compact high-performance electro-optic (E-O) plasmonic switch constructed in a directional coupler like structure, including a plasmonic waveguide and an optical .

Coupler configuration with a taper along the width: (a) xy plane and (b) xz plane. Region ‘1’, ‘2’ and ‘3’ signifies silicon slab waveguide, coupler and HDLPW respectively. The HDLPW starts from a plane at x= by:   We propose and investigate the performance of the plasmonic directional couplers based on two dimensional multi-slit plasmonic waveguides, employing the finite difference time domain simulation method. The idea behind the directional properties of the directional couplers is the interference of two wave components, in and out of phase, at the Cited by: 6. Ultra-fast all-optical plasmonic switching in telecom wavelength realized. and 1/ τ ω is the waveguide coupling loss. At the resonance frequency In this paper, an all-optical plasmonic switch based on metal–insulator–metal (MIM) nanoplasmonic waveguide with a Kerr nonlinear ring resonator is introduced and investigated.

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 nm bandwidth around µm. The device is very compact .
