The periodically poled LiNbO 3 (PPLN) based optical parametric amplifier (OPA) is a technology that contributes to the construction of multi-band wavelength-division multiplexing (WDM) optical netw…
A periodically poled LiNbO 3 (PPLN)-based phase-sensitive amplifier (PSA) has the potential of ultra-low-noise and high-gain optical amplification. For the wideband operation of PSAs in optical fib…
This article proposes an optical parametric amplifier (OPA), as an inline-repeater, using a periodically-poled-LiNbO 3 (PPLN) waveguide with over-10-THz amplification bandwidth, and also presents w…
A phase-sensitive amplifier (PSA) has the potential of low-noise optical amplification and nonlinear phase noise mitigation. For PSA operation, the chromatic dispersion (CD) that causes gain ripple…
