Abstract

A bias-free two-section Y-branch directional coupler modulator with high linearity based on domain-inverted modulation is fabricated and tested. 25 wt. % AJLS102/APC is used as an active core layer with an experimentally confirmed device r 33 value of 56 pm V at 1.59 μ m . The fabricated device shows an extinction voltage of 4 V . A two-tone test is performed to demonstrate 64 dB distortion suppression at 25% modulation depth, which is 22 dB higher than a conventional Mach–Zehnder modulator.
