The Laguerre-Gaussian (LG) beam demonstrates great potential for optical communication due to its orthogonality between different eigenstates, and has gained increased research interest in recent years. Here, we propose a dual-output mode analysis me

The atmospheric turbulence disturbs the phase fronts of orbital angular momentum (OAM) beams, which significantly affects the detection of beam modes. In this paper, we propose a method based on the convolutional neural network (CNN) to detect OAM mo

Measurement of the plasma frequency of a semiconductor film using broadband surface plasmon is demonstrated in this paper. We theoretically deduce a formula about the relation between plasma frequency and characteristic surface plasmon frequency. The
