Much attention has been focused on the use of scalar modes for space division multiplexing (SDM). Alternative vector mode bases offer another solution set for SDM, expanding the available trade-offs in system performance and complexity. We present two types of ring core fiber conceived and designed to explore SDM with fibers exhibiting low interactions between supported modes. We review demonstrations of fiber data transmission for two separate vector mode bases: one for orbital angular momentum (OAM) modes and one for linearly polarized vector (LPV) modes. The OAM mode demonstrations include short transmissions using commercially available transceivers, as well as kilometer length transmission at extended data rates. The LPV demonstrations span kilometer length transmissions at high data rate with coherent detection, as well as a radio over fiber experiment with direct detection of narrowband signals.

Fig.2  Refractive index profile of (a) ring core fiber showing the design (red) and the measured profile (blue), and (b) an elliptical ring core fiber showing the measured profile along the two axis of the ellipse

Fig.4  Setup for transmission experiments. In experiments with commercial transceivers, OAM0 uses OOK transceiver with direct detection, while OAM±1 uses QPSK transceiver with coherent detection. In experiments with a real-time oscilloscope, QPSK with coherent detection is used on both OAM0 and OAM±1
Fig.5  Setup for transmission experiments with LPV modes. In wideband experiments, QPSK data is transmitted on all modes and coherent detection is used. In narrowband radio over fiber experiments, only four channels are populated: inputs 5 and 6 are unused and input 2 is modified to generate LPV11a,x rather than LPV21a,x.
