Polarization- and wavelength-agnostic nanophotonic beam splitter [PDF]
Scientific Reports, 2019 AbstractHigh-performance optical beam splitters are of fundamental importance for the development of advanced silicon photonics integrated circuits. However, due to the high refractive index contrast of silicon-on-insulator platforms, state-of-the-art nanophotonic splitters are hampered by trade-offs in bandwidth, polarization dependence and ...
