Noise Analysis of Second-Harmonic Generation in Undoped and MgO-Doped Periodically Poled Lithium Niobate
Figure 3
Power fluctuations of fundamental and SH
waves in undoped PPLN crystal
measured in the time domain. It is shown that the SH wave has higher peak-to-peak fluctuation than
that of the fundamental wave; and for either wave, the waveguide leads to
higher noise than the bulk crystal.
