High harmonic optomechanical oscillations in the lithium niobate photonic crystal nanocavity

We explore the optomechanical coupling in an on-chip lithium niobate (LN) photonic crystal nanocavity. A mechanical frequency shift and nonlinear mechanical oscillations are observed with the intracavity power increasing. A 14th harmonic oscillation is generated at the intracavity power of 430 μW in...
