Electro-Optic Mode Converter

The Versawave 40 & 50 Gb/s Amplitude Modulators represent a revolutionary method for modulating CW laser light into data carrying optical pulse trains. By employing proprietary GaAs technology, the Versawave modulators establish new benchmarks for low drive voltage, ultra-wide bandwidth, and chirp-free operation within a small footprint.

The innovative and IP protected design of Versawave’s modulators exploit the unique material properties of GaAs to provide chirp free modulation. By using a unique polarization mode converter approach, Versawave eliminates many of the intrinsic limitations of designs based on Mach-Zehnder and other electro-absorption architectures. In addition, the Versawave Amplitude Modulators are able to deliver best-in-class performance over the entire Telcordia GR-468 environmental range without the need of a thermo-electric cooler (TEC).
