Abstract
A combination of non-volatile and volatile integrated functional materials with a multilayer/BEOL capability of SiN and the already mature silicon platform is presented. In this work, an actively reconfigurable 1D photonic crystal multi-channel filter based on Si-on-insulator and liquid crystal platforms is demonstrated with extraordinary large quality factor, Q ∼ 10^4. A complete study and design of an optical routing and multilevel volatile photonic memory based on graphene capacitor concept for future high performance computing using Silicon rich nitride is shown with a bandwidth of 64 GHz and energy power consumption per bit as low as 0.22 pJ. Furthermore, different chalcogenide phase change materials exploiting amplitude or phase modulation are explored for different applications in the two main communication bands, C and O bands as non-volatile materials.
About Joaquin Faneca
Joaquin Faneca finished his B.Sc. in Physics at Universidad de Sevilla and his Master degree in new Photonic Technologies at Universidad Complutense de Madrid. Afterwards, he was awarded with the research fellowship from EPSRC (UK) to pursue the Ph.D. research project in photonic integrated circuits between the University of Southampton, the University of Exeter and co-funded by Lumentum Operations LLC. He has been involved in the design, simulation, fabrication, and characterization of actively tunable devices based on Si and Silicon Nitride platform combined with reconfigurable materials such as phase change materials, liquid crystals and graphene which will be used as a key component of photonic systems. He recently joined IMB to develop a photonic integrated circuit process design kit in the visible range of the spectrum.
