Phase-matched five-wave mixing in zinc oxide microwire.

ABSTRACT: High-order wave mixing in solid-state platforms gather increasing importance due to the development of advanced lasers and integrated photonic circuit for both classical and quantum information. However, the high-order wave mixing is generally inefficient in solids under weak pump. Here, we observed the presence of phase matching of five-wave mixing (5WM) propagating in a zinc oxide (ZnO) microwire. The 5WM signal is enhanced by 2-3 orders of magnitude under the phase matching conditions, reaching an absolute conversion efficiency of 1.7 × 10^-13 when the peak pumping power density is about 10⁶ W/cm². The propagation of multiple nonlinear signals, including sum frequency generation, third harmonic generation, four-wave mixing etc., benefited from both the la
