Most of the waveguides feature two-dimensional guidance, which limits the extension of directed light in two directions, and allows light propagation in only one direction. When the input light is in. The fundamental Waveguides Mode is the mode with the lowest cut-off frequency. However, for metal-clad structures, the high losses in strong light confinement and exciton quenching in nearby active materials pose issues for their use in integrated photonics. The light from the HCG waveguide is then out-coupled after propagation by an identical element, collected by a long working distance objective with an effective focal length of f=2mm and numerical aperture NA=0.5 (Mitutoyo 100 M Plan Apo NIR) and projected onto a camera.
