Large-area Fabry-Perot modulator based on electro-optic polymers

摘要

We present a large-area electro-optic Fabry-Perot modulator utilizing a photoaddressable bis-azo polymer placed between two dielectric mirrors with an open aperture of 2 cm. A modulation efficiency of 1percent at an effective modulation voltage of 20 V for a wavelength of 1.55 (mu)m is demonstrated. By comparing distance tuning of the cavity with wavelength tuning, an effective electro-optic coefficient of -7 pm/V is measured.
