Synthetic parity-time symmetry breaking in a single microcavity
Fangxing Zhang, Yaming Feng, Li Ge +1
Non-Hermitian systems based on parity-time (PT) symmetry reveal rich physics beyond the Hermitian regime. So far, realizations of PT-symmetric systems have been limited to the spat…
Passive thermal fine-tuning of whispering gallery mode for nonlinear optics in a microcavity
Yaming Feng, Yuanlin Zheng, Fangxing Zhang +3
Whispering gallery mode (WGM) microcavities strongly enhance nonlinear optical processes like optical frequency comb, Raman scattering and optomechanics, which nowadays enable cutt…
Nonlinear Negative Refraction by Difference Frequency Generation
Jianjun Cao, Dongyi Shen, Yaming Feng +1
Negative refraction has attracted much interest for its promising capability in imaging applications. Such an effect can be implemented by negative index meta-materials, however, w…
Metal-Free Flat Lens Using Negative Refraction by Nonlinear Four-wave Mixing
Jianjun Cao, Yuanlin Zheng, Yaming Feng +2
A perfect lens with unlimited resolution has always posed a challenge to both theoretical and experimental physicists. Recent developments in optical meta-materials promise an attr…
