【Abstract】 From the theory of quasi- phase- matched second harmonic generation, a theoretical analysis on errors, which departure from ideal quasi phase matched LN waveguides with ferroelectric domain inversion gratings, is given. The errors in the domain inversion grating are analyzed, and their effects on the output power of the second harmonic generated are found.更多还原
