The integrated optical modules for quantum communication developed by Fraunhofer Heinrich Hertz Institute (HHI) have been selected as one of the “Top 20 photonics technology picks for 2021” by the renowned journal Laser Focus World. This technology allows researchers to combine known material systems for quantum technology directly with photonic integrated circuits, while maintaining the performance of the micro-optical components and is already being used in the QuNET initiative funded by the German Federal Ministry of Education and Research and in the EU projects UNIQORN, 3PEAT, POETICS and TERAWAY.

The publication entitled "A platform approach towards hybrid photonic integration and assembly for communications, sensing, and quantum technologies based on a polymer waveguide technology" written by Moritz Kleinert, Madeleine Nuck, Hauke Conradi, David de Felipe, Martin Kresse, Walter Brinker, Crispin Zawadzki, Norbert Keil, Martin Schell is online. 

In this publication, the authors present functionalities of photonic integrated circuits and a generic assembly approach for their hybrid integration with other components in the polymer waveguide platform PolyBoard. In addition to standard integrated optics capabilities, the PolyBoard approach allows for the realization of flexible interconnects, the fabrication of multilayer waveguide structures with low intra-layer coupling losses, and the integration of bulk optical crystals in on-chip free-space sections. These functionalities enable PICs with applications ranging from communications, via sensing, to quantum technology. The semiautomated assembly process presented in the second part of this paper ensures the compatibility of all individual functionalities and the scalability of the developed approaches towards production.

A new publication entitled "2D Optical Phased Arrays for Laser Beam Steering Based On 3D Polymer Photonic Integrated Circuits" is now online! 

The authors, Adam Raptakis, Lefteris Gounaridis, Madeleine Weigel, Moritz Kleinert, Michalis Georgiopoulos, Elias Mylonas, Panos Groumas, Christos Tsokos, Norbert Keil, Hercules Avramopoulos, Christos Kouloumentas propose a novel concept for the implementation of 2-dimensional (2D) optical phased arrays (OPAs) with end-fire waveguides as antenna elements (AEs), and we present its theoretical model and experimental proof. The concept is based on the use of 3-dimensional (3D) photonic integrated circuits (PICs) with multiple waveguiding layers on the PolyBoard platform. In their simplest form, the 3D PICs comprise AEs at different layers, vertical and lateral couplers for the distribution of light among the AEs, and phase shifters for the execution of the 2D beam scanning process.
