Tunable Mode-Locked Laser Photonic Integrated Circuit Using Intracavity Phase Modulators

A 30 GHz mode-locked laser in PIC is presented using InP-based active-passive integration technology. The 2.8 mm long cavity contains phase modulators enabling sub-nm fine tuning of the lasing spectrum which is experimentally demonstrated.This project has received funding from the European Union’s Horizon 2020 research and innovation programme under the Marie Sklodowska-Curie grant agreement No 642355 “FiWiN5G” and Spanish Ministerio de Economia y Competitividad DiDACTIC project TEC201347753-C3-3-R
