Titel
A travelling wave electrode Mach-Zehnder 40 Gb/s demultiplexer based on strain compensated GaInAs/AlInAs tunnelling barrier MQW structure
Abstract
In this work high bandwidth and polarization independence were tackled by employing a travelling wave electrode and a tunnelling barrier QW (TBQW) structure, respectively, as the basic guidelines in the design of the switching element, a Mach-Zehnder interferometer (MZI). With a small variation of the waveguide network connecting the MZI either a time division demultiplexer (DEMUX) or a modulator were fabricated. The development of the DEMUX is part of the European ACTS HIGHWAY project.
