Non-maximal polarization-entangled photons with spectrally-varying non-maximality
Mao Tong Liu, Han Chuen Lim · 2015
We pump two periodically-poled lithium niobate waveguides of different lengths in a Sagnac loop to produce photons with spectrally-varying non-maximal polarization entanglement for the first time. The desired non-maximality is selectable by optical wavelength filtering.
