Efficient polarization squeezing as a resource for quantum communication
J. Heersink, Vincent Josse, Gerd Leuchs, Ulrik L. Andersen · 2005
We report on a novel and efficient source of polarization squeezing using a single pass through an optical fiber. Simply passing this Kerr squeezed beam through a carefully aligned /spl lambda//2 waveplate and splitting it on a polarization beam splitter, we find polarization squeezing of up to 5.1/spl plusmn/0.3 dB. The experimental setup allows for the direct measurement of the squeezing angle.
