High resolution meta-stereomicroscope based on birefringent meta-optics
Liheng Yan, Haowen Liang, Emiliano R. Martins +5
Achieving both high lateral and high depth resolution is a longstanding goal in stereomicroscopy. Although meta-optics have revolutionized lens design by alleviating the physical c…
Imaging of objects through a thin scattering layer using a spectrally and spatially separated reference
Xiaoqing Xu, Xiangsheng Xie, Abhilash Thendiyamma +5
Incoherently illuminated or luminescent objects give rise to a low-contrast speckle-like pattern when observed through a thin diffusive medium, as such a medium effectively convolv…
3D Object Imaging through Scattering Media
Xiangsheng Xie, Huichang Zhuang, Hexiang He +4
Human ability to visualize an image is usually hindered by optical scattering. Recent extensive studies have promoted imaging technique through turbid materials to a reality where…
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…
