Abstract

The exploitation of the spatial domain with the concept of multiple-input multiple-output (MIMO) is a promising approach to further improve the cost efficiency in fiber-optic communications. Historically, the first optical MIMO systems utilized multi-mode couplers for the purpose of mode multiplexing (MUX) and demultiplexing (DEMUX). However, their high insertion losses and asymmetries demand for alternative components. Nowadays, next to optical couplers, photonic lanterns have become considerably more attractive offering low insertion losses and being able to excite individual modes. Therefore, they are in the focus of this contribution. A setup of 6-port photonic lanterns is evaluated by measurements and compared with other multiplexing components. The measurement results and the simulated bit-error rate performances highlight that photonic lanterns are well-suited for optical MIMO communications.
