Highly efficient electro-optic polymer modulator operating in visible wavelength

The modulator using organic electro-optic (EO) polymers has excellent optical properties such as high-speed operation and low driven voltage. The modulator using EO polymer were previously proposed and demonstrated at communication wavelength. We prepared the EO polymer to demonstrate the modulator operated at visible wavelength. Our synthesized EO polymer has low optical loss at operating wavelength. The Mach-Zehnder modulator was fabricated to evaluate modulation properties. In this study, we successfully demonstrated the highly efficient modulator using EO polymer at visible wavelength.
