Controlling quasi-parametric amplifications: From multiple PT-symmetry phase transitions to non-Hermitian sensing
Xiaoxiong Wu, Kai Bai, Penghong Yu +7
Quasi-parametric amplification (QPA) is a nonlinear interaction in which the idler wave is depleted through some loss mechanism. QPA plays an important role in signal amplification…
