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.
