摘要

A novel method is presented to enhance the resonant transmission contrast ratio in metal-insulator-metal (MIM) sidecoupled-cavity waveguide.The finite difference time domain (FDTD) method is used to simulate and study the optical properties of the filter based on double side-coupled cavities structure with optofluidics pump system (OPS).This system provides a flexible way to change wavelength in the optical filter.In the numerical simulation,the resonant wavelengths from 1000 um to 1550 um are analyzed.We find that the double side-coupled cavities structure with OPS has higher onresonance transmittance and better wavelength selectivity than the single side-coupled cavity structure with OPS.
