Evolution of orbital angular momentum in a soft quasi-periodic structure with topological defects
Wang Zhang, Jie Tang, Peng Chen +4
We propose a quasi-periodic structure (QPS) with topological defects. The analytical expression of the corresponding Fourier spectrum is derived, which reflects the combined effect…
Light Reconfigurable Geometric Phase Optical Element with Multi-stable States
Xiao-Qian Wang, Alwin Ming-Wai Tam, Wei-Qiang Yang +9
We present the design methodology of a light reconfigurable geometric phase optical element with multi-stable diffraction efficiency states, enabled by a photoresponsive self-organ…
Evolution and spatial distribution of Brillouin backscattering associated to hybrid acoustic modes in sub-wavelength silica microfibers
Wei Luo, Hong-qian Cao, Yong-kang Dong +3
The spectral evolution and spatial distribution of backscattered Brillouin signals is experimentally investigated in sub-wavelength silica microfibers. The Brillouin spectrum evolu…
Broadband optical-fiber-compatible photodetector based on a graphene-MoS2-WS2 heterostructure with a synergetic photo-generating mechanism
Yi-feng Xiong, Jin-hui Chen, Fei Xu
Integrating two-dimensional (2D) crystals into optical fibers can grant them optoelectronic properties and extend their range of applications. However, our ability to produce compl…
