Experimental Research on Automatic Alignment and Control Algorithm of Spatial Light-Fiber Coupling
This study aims to solve the difficulties in the coupling between space light and single-mode fiber (SMF) in free-space optical communication. A fiber coupler based on two-dimensional (2D) piezoelectric ceramics was developed, which uses the stochastic parallel gradient descent (SPGD) algorithm to r...
