Precise and high-speed lightwave control for huge-capacity transmission and advanced optical signal processing

摘要

We present recent progress of high-speed Mach-Zehnder interferometer based device technologies for advanced modulation formats, and high-performance optical switching. Multi-level quadrature amplitude modulation signal can be synthesized by using parallel Mach-Zehnder modulators. Mach-Zehnder interferometer based switching devices can provide guard-time-free switching with 10-Gb/s signals.
