Abstract
A new antenna-coupled electrode electro-optic (EO) modulator for direct conversion from D-band wireless signals to optical signals is analyzed and designed. In this EO modulator, the modulation efficiency in the D-band is increased by using the stacked structure of a thin LiNbO3 film and fluorine-based resin substrate. In the simulation, modulation electric field of about 2500 times larger than received D-band wireless signal on the antenna surface was observed along the resonant standing-wave resonant electrode, which enables to have an effective signal conversion from D-band wireless to optical signals.
