Abstract

We discuss optical transmission using homogeneous, single-mode, multicore fibers. We first describe the key fiber properties that can affect transmission, such as intercore crosstalk and the variation of propagation delay between cores, and the consequences of these properties on spatial super-channel transmission. We then describe a series of experiments and demonstrations of system features including self-homodyne detection and joint spatial superchannel modulation before discussing their suitability to high-capacity transmission.
