Electro-optic polymers for visible light

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.
