Ultra-Wideband WDM Transmission Using PPLN-Based Optical Parametric Amplifier and Wavelength Converter
This paper reviews ultra-wideband inline-amplified WDM transmission systems, including bandwidth extension to the U-band, using optical parametric amplification and waveband conversion based on our high-efficiency periodically poled lithium niobate (PPLN) <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">$\chi^{(2)}$</tex>-nonlinear waveguides.
