Brewster反射的矢量涡旋产生和相位奇异性
Vectorial vortex generation and phase singularities upon Brewster reflection
摘要：
实验证明了聚焦圆偏振光经介质基片的布儒斯特反射后，出现了具有相位奇异性的纯方位偏振矢量涡旋光束。这种效应源于布儒斯特定律中描述的菲涅耳反射系数的偏振特性。这种效应的一个令人惊讶的结果是，反射场的笛卡尔分量在布鲁斯特角处获得局部相位奇点。我们的观测结果对于偏振显微镜至关重要，并为基于自旋-轨道耦合产生奇异光态开辟了新的途径，而无需复杂的光学元件。
英文摘要：
We experimentally demonstrate the emergence of a purely azimuthally polarized vectorial vortex beam with a phase singularity upon Brewster reflection of focused circularly polarized light from a dielectric substrate. The effect originates from the polarizing properties of the Fresnel reflection coefficients described in Brewster's law. An astonishing consequence of this effect is that the reflected field's Cartesian components acquire local phase singularities at Brewster's angle. Our observations are crucial for polarization microscopy and open new avenues for the generation of exotic states of light based on spin-to-orbit coupling, without the need for sophisticated optical elements.
