Time reversed optical waves by Arbitrary Vector spatiotemporal field generation.
Nature communications, 2020Co-Authors: Mickael Mounaix, Nicolas K. Fontaine, David T. Neilson, Roland Ryf, Haoshuo Chen, Juan Carlos Alvarado-zacarias, Joel CarpenterAbstract:Lossless linear wave propagation is symmetric in time, a principle which can be used to create time reversed waves. Such waves are special “pre-scattered” spatiotemporal fields, which propagate through a complex medium as if observing a scattering process in reverse, entering the medium as a complicated spatiotemporal field and arriving after propagation as a desired target field, such as a spatiotemporal focus. Time reversed waves have previously been demonstrated for relatively low frequency phenomena such as acoustics, water waves and microwaves. Many attempts have been made to extend these techniques into optics. However, the much higher frequencies of optics make for very different requirements. A fully time reversed wave is a volumetric field with Arbitrary amplitude, phase and polarisation at every point in space and time. The creation of such fields has not previously been possible in optics. We demonstrate time reversed optical waves with a device capable of independently controlling all of light’s classical degrees of freedom simultaneously. Such a class of ultrafast wavefront shaper is capable of generating a sequence of Arbitrary 2D spatial/polarisation wavefronts at a bandwidth limited rate of 4.4 THz. This ability to manipulate the full field of an optical beam could be used to control both linear and nonlinear optical phenomena. Truly Arbitrary spatiotemporal wavefront shaping has many potential applications in optics. Here the authors develop a system capable of Arbitrary waveshaping to the extent of full time reversal of spatiotemporal optical beams.

Generation of Arbitrary Vector vortex beams on hybrid-order Poincaré sphere based on liquid crystal device.
Optics express, 2019Co-Authors: Shaozhen Lou, Yaqin Zhou, Yide Yuan, Tiegang Lin, Fan Fan, Xiaoqian Wang, Huihui Huang, Shuangchun WenAbstract:We propose theoretically and verify experimentally a method of using electrically tunable liquid crystal q-plate and wave plate for generating Arbitrary Vector vortex beams on a hybrid-order Poincare sphere (HyOPS). The generated Vector vortex beam is verified and shows decent agreement with the prediction. This method brings many advantages, such as high conversion efficiency, good electrical controllability, and integration. This system can provide fundamental optical system support for various structured beam applications.

Electrically driven generation of Arbitrary Vector vortex beams on the hybrid-order Poincaré sphere.
Optics letters, 2018Co-Authors: Ruisi Wang, Weixing Shu, Hailu Luo, Shizhen Chen, Jin Zhang, Shuangchun WenAbstract:We propose a simple, efficient, and fast tunable method to generate Arbitrary Vector vortex beams on the hybrid-order Poincare sphere in an electrically driven way. The scheme incorporates the tunability and switching capabilities of liquid crystals into dielectric metasurfaces to form an efficient Vector vortex beam generator. By applying certain voltages on the liquid crystal phase retarder, the generator converts a linearly polarized Gaussian beam into any desirable Vector vortex beams. We demonstrate that the evolution route of the corresponding Vector vortex states is just a closed circuit on the hybrid-order Poincare sphere when the phase retardation varies from 0 to 2π. Several special cases are selected to demonstrate our scheme, and the experimental results coincide well with the theoretical predictions.

Generation of Arbitrary Vector vortex beams on hybrid-order Poincaré sphere
Photonics Research, 2016Co-Authors: Zhenxing Liu, Yuanyuan Liu, Yachao Liu, Weixing Shu, Hailu Luo, Shuangchun WenAbstract:We propose theoretically and verify experimentally a method of combining a q-plate and a spiral phase plate to generate Arbitrary Vector vortex beams on a hybrid-order Poincare sphere. We demonstrate that a Vector vortex beam can be decomposed into a Vector beam and a vortex, whereby the generation can be realized by sequentially using a q-plate and a spiral phase plate. The generated Vector beam, vortex, and Vector vortex beam are verified and show good agreement with the prediction. Another advantage that should be pointed out is that the spiral phase plate and q-plate are both fabricated on silica substrates, suggesting the potential possibility to integrate the two structures on a single plate. Based on a compact method of transmissive-type transformation, our scheme may have potential applications in future integrated optical devices.
