Electro-optic and Electro-absorption modulators

The main subjects of the research group in the modulator area have been the electromagnetic modeling of traveling wave lithium niobate Mach-Zehnder modulators for long-haul fiber transmission systems, their design and system-oriented modeling (cooperation with Pirelli Optical Systems, Pirelli Corning, Pirelli Labs); the physics-based, EM and system-oriented modeling of electroabsorption and electrooptic modulators on semiconductor substrates, and the experimental electro-optic characterization up to 40 GHz of electrooptic and electroabsorption modulators. More recently, the research has been extended to the investigation an modeling of electro-optic modulator for Si photonic platforms (both conventional and based on Silicon Organic Hybrid or plasmonic approaches) and for InP photonic platforms (cooperation with Huawei).
