1. Space-Division-Multiplexing Platform for a Delayed-Choice Experiment
University essay from Linköpings universitet/InformationskodningAbstract : This master’s thesis explores a space-division-multiplexing (SDM) platform fora delayed-choice experiment. SDM is a multiplexing technique for optical datatransmission that employs spatial modes in a multi- or few-mode fiber to increasethe transmission capacity. The spatial modes can thus be used as separate channels. READ MORE
