并行偏振态产生

Parallel Polarization State Generation

Alan She, Federico Capasso

摘要:

偏振的控制是光的基本性质,具有广泛的科学和技术兴趣。产生任意时变偏振态(SOP)的一般问题一直通过一系列线性变换(即矩阵的乘积)在数学上表述,从而施加串行架构。在这里,我们展示了一个矩阵的总和所描述的并行架构。该理论是通过使用一个数字调制器件调制激光器的空间分离的偏振分量,随后进行光束组合的实验证明。该方法大大扩展了偏振控制工程器件的参数空间。因此,诸如速度、稳定性和光谱范围等性能特性完全由光强度调制技术决定,包括吸收、反射、发射和散射。这为偏振态产生(PSG)开辟了重要的前景,具有独特的性能特点,并在光谱椭圆偏振,光谱偏振,通信,成像和安全的应用。

英文摘要:

The control of polarization, an essential property of light, is of wide scientific and technological interest. The general problem of generating arbitrary time-varying states of polarization (SOP) has always been mathematically formulated by a series of linear transformations, i.e. a product of matrices, imposing a serial architecture. Here we show a parallel architecture described by a sum of matrices. The theory is experimentally demonstrated by modulating spatially-separated polarization components of a laser using a digital micromirror device that are subsequently beam combined. This method greatly expands the parameter space for engineering devices that control polarization. Consequently, performance characteristics, such as speed, stability, and spectral range, are entirely dictated by the technologies of optical intensity modulation, including absorption, reflection, emission, and scattering. This opens up important prospects for polarization state generation (PSG) with unique performance characteristics and applications in spectroscopic ellipsometry, spectropolarimetry, communications, imaging, and security.
