An Ultra-Compact Design of Plasmonic Memristor with Low Loss and High Extinction Efficiency Based on Enhanced Interaction between Filament and Concentrated Plasmon

We present a numerical design of the plasmonic memristive switching device operated at the telecommunication wavelength of 1.55 μm, which consists of a triangle-shaped metal taper mounted on top of a Si waveguide, with rational doping in the area below the apex of the taper. This device can achieve optimal vertical coupling of light energy from the Si waveguide to the plasmonic region and, at the same time, focus the plasmon into the apex of the metal taper. Moreover, the area with concentrated plasmon is overlapped with that where the memristive switching occurs, due to the formation/removal of the metallic nano-filament. As a result, the highly distinct transmission induced by the switching of the plasmonic memristor can be produced because of the maximized interactions between the filament and the plasmon. Our numerical simulation shows that the device hasa compact size (610 nm), low insertion loss (~1 dB), and high extinction efficiency (4.6 dB/μm). Additionally, we point out that stabilizing the size of the filament is critical to improve the operation repeatability of the plasmonic memristive switching device.

Iot Based Smart Switch Board Technology For Smart Home

To overcome the limitations of the traditional switch board, a new system equipped with latest technologies has been developed as Smart Switch Board and which is the smarter version compared to traditional Switch Boards. An IOT based switching device has been developed and which to be controlled via Blynk application. This smart device is very useful for handicapped persons. The smart switch meter has been used to control the smaller areas if it is connected through the router. It makes the system more secured as it is working through router’s IP address. Physical contact is not required to operate; it ensures reliability and safety from fire accidents. The Hardware component are quite cheap and easy to replace.
