Light can be tailored to carry angular momentum well beyond the restriction of its two spin states, left- and right-circularly polarized light, by imbuing it with orbital angular momentum (OAM). OAM is controlled by imparting finer and finer azimuthal phase gradients, twisting the wavefront ever...

轨道角动量(Orbital Angular Momentum,OAM)表征出具有相位因子为exp(jlφ)的螺旋相位波前结构的自然属性[2]。OAM作为一种不同于相位、幅度、极化的调制维度被引入到无线通信中,可以有效地提高通信系统的容量和效率。螺旋透镜[3]、超表面[4]、螺旋相位板[5]等光领域OAM波束的产生方法很难全部应用于微波段的无线通...
Here, we elucidate that possibility, addressing orbital angular momentum (OAM) entanglement in ultrafast processes. In the correlated process non-sequential double ionization (NSDI) we demonstrate robust photoelectron entanglement. In contrast to commonly considered continuous variables, the discrete OAM ...
Orbital angular momentum (OAM) from lasers holds promise for compact, at-source solutions for applications ranging from imaging to communications. However, conjugate symmetry between circular spin and opposite helicity OAM states (±ℓ) from convention
