Organic electro-optic (EO) polymers are promising candidates for high performance modulator. An EO polymer modulator has excellent optical properties such as low driven voltage and high-speed operation. We successfully developed an EO polymer to demonstrate modulator for visible wavelength. A modulator was demonstrated and evaluated using developed EO polymer at wavelength 640nm. As results of applying a voltage to the fabricated modulator, the voltage-length product 0.52 Vcm was obtained. This is much more efficient than the conventional modulator for near-infrared 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.
We developed a high-performance EO polymer for visible light by adopting figures of merit (FOMs) including wavelength factors to compare the performance of EO polymers over a wide wavelength range. We found EO polymers whose FOMs at 640 nm are larger than those at 1550 nm of the C-band EO polymer. A modulator using the EO polymer for visible light gives that the modulator’s figure of merit, VpiL is as small as 0.65 V·cm, which is smaller than the typical value of C-band EO polymer modulators.
