Generation of nonlinear vortex precursors
Yue-Yue Chen, Xun-Li Feng, Chengpu Liu
We numerically study the propagation of a few-cycle pulse carrying orbital angular momentum (OAM) through a dense atomic system. Nonlinear precursors consisting of high-order vorte…

The origin of the Redshift Spikes in the reflection spectrum of a Few-cycle Pulse in a Dense Medium
Yue-Yue Chen, Xun-Li Feng, Zhi-Zhan Xu +1
We give a detailed description about the reflected spectrum of a few-cycle pulse propagating through a resonant dense medium. An unexpected low-frequency spike appeared in the red…

Strongly interacting and highly entangled photons in asymmetric quantum well with resonant tunneling
Shuangli Fan, Hui Sun, Xun-Li Feng +4
We propose an asymmetric quantum well structure to realize strong interaction between two slow optical pulses. The linear optical properties and nonlinear optical responses associa…
