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 ...

A variable partially polarizing beam splitter [PDF]
Review of Scientific Instruments, 2016 We present designs for variably polarizing beam splitters. These are beam splitters allowing the complete and independent control of the horizontal and vertical polarization splitting ratios. They have quantum optics and quantum information applications, such as quantum logic gates for quantum computing and non-local measurements for quantum state ...
