Parabolic dielectric reflector for extreme on-chip spot-size conversion with broad bandwidth
Laureano Moreno-Pozas, Miguel Barona-Ruiz, Robert Halir +5
Spot-size converters are key for efficient coupling of light between waveguides of different sizes. While adiabatic tapers are well suited for small size differences, they become i…
