Efficient, watt-level frequency doubling and optical parametric amplification on periodically poled lithium niobate ridge waveguide

We have developed the MgO: PPLN ridge waveguide modules for efficient second harmonic generation output and optical parametrical amplification at telecom wavelength. High efficient and high damage resistance of developed MgO: PPLN waveguide modules have enabled efficient optical parametric amplification with >16dB intrinsic gain for the input signal.
