Hybrid photonic integration enables the realization of complex PICs with an optimal combination of materials to realize the various photonic functionalities. Fraunhofer HHI’s hybrid integration platform PolyBoard allows for the combination of passive polymer waveguides, micro-optical benches and active semiconductor elements. The transparency from the visible to the infrared enables tunable lasers, highly efficient filters as well as on-chip nonlinear and nonreciprocal optics across this broad spectrum. In combination with other functionalities of the platform, complex PIC for various application fields, including communications, sensing and especially quantum technologies, were realized and will be presented in the talk.
Moritz Kleinert is a project manager in the fields of integrated photonics and quantum technologies at Fraunhofer HHI. He joined HHI in 2013 after obtaining Bachelor’s and Master’s degrees from TU Berlin. In 2018 he received a Ph.D. in physics for his work on the integration of graphene in photonic integrated circuits for novel optoelectronic devices. He holds several patents related to integrated optics and is author/co-author of more than 50 papers in international journals and conference contributions. Currently, he is project manager in the EU QT flagship project UNIQORN and the German QuNET initiative and responsible for the development of hybrid photonic integrated circuits for quantum communications.
