High performance optical systems using MIM based plasmonic structures

Abstract

In this paper, the design of high performance optical systems based on MIM based plasmonic structures is proposed. Using a design methodology based on optimization functions, two novel components are proposed: demultiplexer and gas sensor. Further optimization of these plasmonic systems, high performance optical demultiplexer is maintained with a narrow line-width down to 4 nm with acceptable power level around 30%. On the other side, highly sensitive optical sensor is proposed with sensitivity up to 2000 nm and a limit of detection down to 10 −4 .

A single-mode tunable plasmonic sensor based on an 8-shaped resonator for cancer cell detection

“…For this reason, we have modified the 8-shaped resonator and proposed the second and third structures which exhibit a single-mode resonance. The proposed plasmonic structure can be fabricated using electron beam lithography (EBL) with adequate exposure time and focused ion beam (FIB) technique 58 . Generally, the fabrication of plasmonic structures can be costly and time-consuming, which can limit their use in some specific applications 56 .…”

Double and triple-wavelength plasmonic demultiplexers based on improved circular nanodisk resonators

“…Various structures and resonator configurations have been recently introduced for plasmonic DeMuxes. [36][37][38][39][40][41][42][43][44][45][46][47][48][49][50][51][52][53] One of the most common types of resonators used to design DeMuxes is circular nanodisk resonator (CNR). CNRs have desirable properties such as easy implementation and tunable resonance frequency.…”
