AMO attained crucial results on co-integration of Aluminium based plasmonic and Si3N4 photonic waveguides
AMO GmbH together with Aristotle University of Thessaloniki and Université de Bourgogne attained crucial results on co-integration of Al based plasmonic and Si3N4 photonic waveguides. The results of these research activities are described in the paper “Aluminum plasmonic waveguides co-integrated with Si3N4 photonics using CMOS processes” which was recently published in Nature Scientific Reports.
The researchers proved the feasibility of co-integrating Aluminum plasmonic waveguides with Si3N4 photonics employing low-cost and fully CMOS compliant material platforms and manufacturing methods. Propagating surface plasmon polariton (SPP) modes over Aluminum waveguides, exposed to water and air have been demonstrated at 1.55 μm with LSPP lengths of 50 and 65 μm, respectively, while air-cladded Aluminum waveguides were also exposed to data traffic transmission experiments validating for the first time their high-quality signal integrity characteristics with 25 Gb/s optical data.
