EO POLYMER-BASED DUAL SLOT WAVEGUIDE MODULATORS

摘要

Electro-optic modulators are disclosed. An electro-optic modulator comprises an electro-optic polymer layer, semiconductor layers, ferroelectric material layers, and electrodes. The semiconductor layers are positioned on each surface of the electro-optic polymer layer. The refractive index of the semiconductor layers in the optical and RF domains is higher than the refractive index of the electro-optic polymer layer in the optical and RF domains. The ferroelectric material layers are positioned on each semiconductor layer opposite the electro-optic polymer layer. The refractive index of the ferroelectric material layers in the RF domain is higher than the refractive indices of both the electro-optic polymer layer and the semiconductor layers in the RF domain. The refractive index of the ferroelectric material layers in the optical domain is lower than the refractive index of the semiconductor layer in the optical domain. The electrodes are positioned on each ferroelectric material layer opposite the semiconductor layer.
