Abstract

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. It is further shown that based on the same physical mechanism multi-dielectric-core composite MDM structures could serve as a novel plasmonic waveguide crossover component with low cross talk and high throughput.

Highlights

  • Today’s semiconductor industry has successfully scaled the dimensions of electronic devices down to the order of ~50 nm

  • Various plasmonic waveguide structures such as metallic stripes [5], metal-dielectric-metal (MDM) and dielectric-metaldielectric (DMD) structures [6,7,8], dielectric-loaded surface plasmon polariton (SPP) waveguides [9], V-shaped metal grooves [10], and Λ-shaped metal wedges [11] have been prototyped as interconnects for information transport

  • We show that the contra-directional coupling between adjacent MDM waveguides with different dielectric cores can be achieved with high coupling efficiency

Summary

Introduction

Today’s semiconductor industry has successfully scaled the dimensions of electronic devices down to the order of ~50 nm. Photonics offers an effective solution to this problem by implementing communications and processing systems based on photonic circuits, which are dictated by diffraction limit (the typical dimension is on the order of ~1 μm) [2]. This implies that electronic and optical devices usually show complementary characteristics in terms of sizes and speed. We will show that contra-directional coupling achieved in plasmonic MDM slot waveguides can be used to realize novel devices with simplified designs. It is shown that based on the same physical mechinism these multi-dielectric-core composite structures could serve as a novel plasmonic waveguide crossover component with low cross talk and high throughput
