  • Abstract
    We achieved 16QAM signal amplification using a PPLN-based PSA with high gain linearity. Phase noise cancellation and an improved SNR were successfully demonstrated. The applicability of the amplification of multi-carrier signals and two orthogonally-polarized signals was also confirmed toward ultra-high spectrally efficient signal amplification.
