论文摘要
光的极化纹理可能反映基本现象,例如拓扑缺陷,并且可以用于工程光束。在创建过程中,应用了三个主要途径:相变的自发外观,通过激发光束转向或介质的结构工程。我们提出了一种方法,该方法在一个平台中使用所有三个方法,其提供优点,这些优点在任何先前的系统中都不同时提供:高级结构工程,具有有效光子相互作用的强耦合冷凝物以及室温和室温和次秒操作。我们通过将晶格的偶极结构与相位检索揭示的非平凡的冷凝物相结合,来证明等离子晶格玻璃晶体冷凝物中的结构壁极化纹理。这些结果为非平衡凝结和极化束的来源的基本研究开辟了新的前景。
Polarization textures of light may reflect fundamental phenomena such as topological defects, and can be utilized in engineering light beams. Three main routes are applied during their creation: spontaneous appearance in phase transitions, steering by an excitation beam, or structural engineering of the medium. We present an approach that uses all three in a platform offering advantages that are not simultaneously provided in any previous system: advanced structural engineering, strong-coupling condensate with effective photonic interactions, as well as room temperature and sub-picosecond operation. We demonstrate domain wall polarization textures in a plasmonic lattice Bose-Einstein condensate, by combining the dipole structure of the lattice with a non-trivial condensate phase revealed by phase retrieval. These results open new prospects for fundamental studies of non-equilibrium condensation and sources of polarization-structured beams.
