Summary
We demonstrate plasmonic induced transparency in a novel metal-dielectric-metal waveguide using elliptical resonators. This technology enables significant light slowing for advanced optical circuits.
Area of Science:
- Photonics and Plasmonics
- Nanotechnology
- Optical Engineering
Background:
- Electromagnetically induced transparency (EIT) is a quantum interference effect.
- Plasmonics offers chip-scale light manipulation capabilities.
- Metal-dielectric-metal (MDM) waveguides are key components in plasmonic circuits.
Purpose of the Study:
- To demonstrate an analogue of EIT in a plasmonic MDM waveguide.
- To propose and numerically investigate a novel MDM structure using elliptical resonators.
- To explore applications in slow-light devices and optical signal processing.
Main Methods:
- Utilizing a finite difference time domain (FDTD) simulation method.
- Designing a 2x2 plasmonic ring resonator with gold and polymethyl methacrylate.
- Investigating the optical properties of an ellipse-shaped side-coupled ring resonator.
Main Results:
- Achieved plasmonic induced transparency with a distinct transparent window at 1550 nm.
- Observed significant slowing of plasmonic mode velocity in MDM waveguide bends.
- Elliptical resonators showed improved performance over circular ones, with a slow-down factor exceeding 30.
Conclusions:
- The proposed MDM waveguide with elliptical resonators effectively demonstrates plasmonic induced transparency.
- The system facilitates substantial light slowing, enabling applications in optical storage and delay.
- This work contributes to the development of highly integrated optical circuits, filters, and switches.
