Abstract

We review the capabilities of optical parametric amplifiers based on periodically poled lithium niobate (PPLN) waveguides for applications in optical communications and quantum information processing. In particular, we discuss recent advances in wavelength-band conversion, broadband amplification, and the generation of squeezed and non-Gaussian states of light. These advances demonstrate the versatility of PPLN-based devices as essential components for future optical networks and optical quantum computing systems.
