Abstract

Future optical systems will require electro-optic (EO) modulators with bandwidths of 100 GHz. For high-speed modulation, a photonic crystal (PhC) waveguide modulator using a ferroelectric thin film has been proposed. Here we report on the design, fabrication and properties of optical intensity modulator and its microwave frequency dependence. The 1.5 mm long BaTiO3 PhC modulator has a figure-of-merit of 2.1 V cm drive voltage-length product, $>$50 GHz 3 dB bandwidth at an operating wavelength of 1560 nm.
