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.
