An atomic Faraday beam splitter for light generated from pump degenerate four-wave mixing in a hollow-core photonic crystal fiber
Ioannis Caltzidis, Harald Kübler, Tilman Pfau +2
We demonstrate an atomic Faraday dichroic beam splitter suitable to spatially separate signal and idler fields from pump degenerate four-wave mixing in an atomic source. By rotatin…

Integrating two-photon nonlinear spectroscopy of rubidium atoms with silicon photonics
Artur Skljarow, Nico Gruhler, Wolfram Pernice +4
We study an integrated silicon photonic chip, composed of several sub-wavelength ridge waveguides, and immersed in a micro-cell with rubidium vapor. Employing two-photon excitation…
