Electro-optic modulators with self-assembled superlattice waveguides
摘要
Abstract
This paper reports a new waveguide electro-optic (EO) modulator with self-assembled superlattice (SAS) electro-optic films. This work focuses on the measurement for the EO coefficient of SAS films and the optimization for the devices structure. In order to have a precise and effective design, we test the angle-dependence of the second harmonic generation of incident laser beam to determine the effective EO coefficient. We study he absorptive loss of electrodes of devices with the optical propagation theory of multi-layered films and optimize the devices structure to obtain the lowest drive voltage. The paper gives the structure of experimental samples and the scanned electronic microscopy (SEM) pictures of our fabricated devices. Finally, 1.0 dB/cm optical propagation loss of the EO modulators is achieved, which agrees with the experimental results.关键词
