论文摘要
我们在倾斜偏振器系统中表现出了一个有趣的巨型光束移位，类似于Imbert-Fedorov移动，在Brewster发射率周围的部分反射中。我们使用广义的理论处理来解释这种巨大的转移，以在倾斜的单轴各向异性材料中进行光束移位，该材料在实验室框架中融合了其光轴的三维方向。我们进一步证明了通过明智地调整输入极化和相应的方向角来证明移动幅度和方向的调节性控制和可调节性。这些发现开辟了使用简单的线性偏振器精确的微米级梁转向的可能性。
We demonstrate an intriguing giant optical beam shift in a tilted polarizer system analogous to the Imbert-Fedorov shift in partial reflection around the Brewster's angle of incidence. We explain this giant shift using a generalized theoretical treatment for beam shift in a tilted uniaxial anisotropic material incorporating the three-dimensional orientation of its optic axis in the laboratory frame. We further demonstrate regulated control and tunability of both the magnitude and direction of the shifts by wisely tuning the input polarization and the corresponding orientation angles. These findings open up the possibility of precise micron-level beam steering using a simple linear polarizer.
