摘要:
We report the observation of second harmonic generation and acoustic‐wave convolution for surface waves onYZ‐cut lithium niobate where the nonlinearity originates with the charge‐particle dynamics in a nearby semiconductor. The second harmonic generation is 28 dB above that obtained from LiNbO3alone, and the convolution output is 24 dB above reports for LiNbO3alone.
