High-Quality Grouped-Wavelength Conversion and Dynamic Switching Using Multiple-QPM LiNbO $_{3}$ and TLA

We demonstrate dynamic grouped-wavelength conversion using multiple quasi-phase-matched LiNbO
₃
modules and a tunable laser diode array. A high signal-to-noise ratio of larger than 45 dB is obtained for the converted signals. The power penalty of the wavelength converter is confirmed to be less than 0.2 dB.
