The Tunable Optofluidics Waveguide Design Based on the Novel Dual Side-Coupled Cavities Plasmonic Structure

Abstract:

We present a tunable wavelength filter in plasmonic metaldielectricmetal (MIM) side-coupled-cavity waveguide with optofluidics pump system proposed to realize tunable mechanism. The peak wavelength can shift by manipulating the length of liquid column and the effective refractive index. The finite difference time domain method is used in the numerically simulated experiment and the resonant wavelengths from 1000 to around 1800nm had been analyzed. The results reveal that the resonant wavelengths are proportional to the liquid volume length and refractive index of liquid in the cavity. This waveguide filter can be used in integrated optical circuits.
