    Integrated optical modules for quantum communication

    Andreas Thoss
    Nov. 17, 2021
    As quantum communication moves from the lab to real life, optical integration will be key. Researchers are already preparing for the transition with the introduction of established...
    FIGURE 1. A schematic side view shows an on-chip free-space section created using two waveguide-coupled GRIN lenses (a). The top view (b) shows two integrated GRIN lenses creating a free-space etalon (highlighted in yellow). The cross-section (c) illustrates a U-groove with integrated GRIN lens; the width and depth of the U-groove match the GRIN lens diameter of 125 µm.
