High-performance InP-based Optical Modulators

摘要

We demonstrate two types of high-speed semiconductor optical modulators operating at 40 Gbit/s with reduced driving voltage. One is a compact Mach-Zehnder modulator module that achieves error-free operation in a push-pull configuration with a peak-to-peak voltage of 1.3 V. The other is an electroabsorption modulator integrated with microwave coplanar waveguides and driven by a voltage as low as 0.79 V.
