Abstract

Periodically poled lithium niobate waveguides (PPLN/W) are considered to be one of the most useful toolboxes for enabling quantum communication experiments. Thanks to the high optical confinement over longer lengths than in bulk configurations (a few cm in our case), such structures provide highly efficient non-linear interactions, i.e., in parametric downconversion, or sum and difference frequency generation regimes. Within the framework of long-distance quantum communication at telecom wavelengths, PPLN/Ws have therefore been proved to be a key ingredient for building ultrabright sources of time-bin, as well as polarization entangled photons, and for photonic quantum interfaces providing coherent wavelength conversions from telecom to visible wavelength range, and conversely. During the presentation, we will discuss some recent experimental advances regarding polarization entanglement sources and quantum interfaces.
