Abstract: A photonic circuit can include a multi-waveguide edge coupler to receive light from an external light source. The edge coupler can include planar waveguides and one or more middle waveguides that separate the planar waveguides. The middle waveguides can couple light and have a tapered shape. The planar waveguides can include multiple thin plates that have sub-wavelength thickness, and can be implemented to shape a mode coupled between an external light source and the photonic circuit.
