SHG tuning curves for waveguide with a QPM period recorded by scanning from short-to-long wavelengths (increasing scan, black solid). The dotted red curve shows the increasing wavelength scan after low pass filtering of the data to remove the Fabry-Pérot features. The inset shows a tuning hysteresis loop around a single Fabry-Pérot feature.
SHG tuning curve envelopes for different input powers.
Output fundamental power (top) and second-harmonic power (bottom) at the detectors as the input power is increased (up curve) and decreased (down curve) at a fundamental wavelength of 1545.41 nm. Note that due to the nonlinear dependence, the second-harmonic power is shown on a logarithmic scale.
Temporal response at 1545.90 nm for different input power levels above highest threshold level in Fig. 3.
