The development of advanced InP-based transmitter PICs of increasing complexity and integrating periodically capacitive-loaded (CL) Travelling Wave Electrode (TWE) Mach-Zehnder modulators is reported and discussed in examples.
The development of InP-based 4- and 8-channel IQ Mach-Zehnder modulator PICs as basic active building blocks in advanced hybrid terabit super-channel OFDM/Nyquist WDM transmitter components is reported for the first time.
High speed InP-based travelling wave electrode (TWE) Mach-Zehnder modulators are presented and their integration capabilities to fabricate next generations of compact and high capacity transmitter components by utilizing so-called “monolithic-on-hybrid” integration approaches are emphasized.
The state-of-the art of medium and large scale InP-based Mach-Zehnder modulator PIC development is reported with regard to commercial fabrication of advanced transmitter components.
The linewidth of an improved 40 GHz modelocked laser diode is investigated. The influence of its operation parameters on linewidth and the resulting performance in a 40Gband-DQPSK system is evaluated.
