Paper Abstract

A metal-insulator-metal voltage tunable filter based on organic electro-optical materials DAST is proposed by using the side-coupled method. The structure consists of two H-type cavities and a rectangular waveguide. The transmission spectra, resonance wavelength distribution curves and the magnetic field distribution of the asymmetric H-type cavities structure filter have been calculated and analyzed by the finite element numerical simulation method. The results show that the filter has the feature of smooth transmission spectra, wide bandwidth (full width at half maxima achieved 754 nm). And the transmittance of the passband is up to 0.968, the transmittance of the stopband can reach 1 × 10−5. The characteristics of the filter can be adjusted not only by changing the structural parameters, but also by applying a control voltage, the adjustability of the filter is increased. Therefore, the filter is of great significance in high-density integrated circuits and nano-optics.
