ABSTRACTIn this paper, some of the activities towards the fabrication of Photonic Integrated Circuits at the COBRA Research Institute are summarized. Firstly, rate equations are used for the understanding of instability and dynamics in multilongitudinal mode semiconductor lasers. Secondly, we report the results of our investigation on broad-bandwidth frequency comb generators based on novel mode-locked InAs/InGaAsP/InP quantum dot laser diodes. In addition, we will show the integration of two-dimensional pillar-based photonic crystal waveguides in an InGaAsP/InP photonic integrated circuit. Keywords: nonlinear dynamics, InP, photonic crystals, modelocking, integrated optics laser, DBR gratings. INTRODUCTIONThe COBRA Research Institute at the University of Technology Eindhoven is active in research in semiconductor materials and semiconductor optical devices. The fabrication of Photonic Integrated Circuits (PICs) in which semiconductor lasers and photonic crystals structures can be built-in, allows photonic systems to be more compact and capable of providing higher performance than with the use of discrete optical components. In addition, they...
