Geometric phase with full-wedge and half-wedge rotation in nonlinear frequency conversion
Feiyan Zhao, Jiantao Lü, Hexiang He +3
When the quasi-phase matching (QPM) parameters of the nonlinear crystal rotate along a closed path, geometric phase will be generated in the signal and idler waves that p…
Adiabatic geometric phase in fully nonlinear three-wave mixing
Yongyao Li, Ofir Yesharim, Inbar Hurvitz +4
In a nonlinear three-wave mixing process, the interacting waves can accumulate an adiabatic geometric phase (AGP) if the nonlinear coefficient of the crystal is modulated in a prop…
Optical Superoscillatory Poisson-Arago Spots
Yanwen Hu, Shenhe Fu, Zhigui Deng +5
Optical diffraction limit has been a long-term scientific issue since Ernst Abbe first introduced the concept in 1873. It is a constraint on the smallest light spot that can be ach…
Ultrafast Optical Signal Processing with Bragg Structures
Yikun Liu, Shenhe Fu, Boris A. Malomed +2
The phase, amplitude, speed, and polarization, in addition to many other properties of light, can be modulated by photonic Bragg structures. In conjunction with nonlinearity and qu…
Nonlinear light propagation in cholesteric liquid crystals with a helical Bragg microstructure
Yikun Liu, Shenhe Fu, Xing Zhu +7
Nonlinear optical propagation in cholesteric liquid crystals (CLC) with a spatially periodic helical molecular structure is studied experimentally and modeled numerically. This per…
Tunable storage of optical pulses in a tailored Bragg-grating structure
Shenhe Fu, Yongyao Li, Yikun Liu +2
Scenarios for controllable creation, trapping and holding of single and multiple solitons in a specially designed nonlinear Bragg grating (BG) are proposed. The setting includes a…
