“…Degenerate LP modes with the same propagation constants need not be excited separately as they will couple to each other in the few mode fiber. Such mode-group selective lanterns that could excite up to the first four LP mode groups have been recently demonstrated [8,9].…”

MIMO less few mode transmission is performed using two spatial channels transmitted through 1 km of two mode graded index fiber at 10 Gb/s modulation rate. The multiplexing and de-multiplexing of the spatial channels are done using air clad photonic lanterns. The power in the two degenerate LP11 modes are added electrically and counted as a single channel. The Q values calculated for the LP01 and LP11 channels are 5.4 and 4.7 respectively. We also show that, the signal degradation due to modal interference can be mitigated by using different laser sources for different spatial channels with some wavelength spacing. The wavelength separation increases the modal beat frequency beyond the detector bandwidth, thus improving the transmission performance. Using two laser sources with a wavelength spacing of 0.2 nm between the spatial modes could improve the Q compared to the case where a single laser source is split between the spatial channels with some extra length of fiber in one of the paths for optical decorrelation.

“…The weak-coupling among different MGs can be exploited to eliminate the need of coherent detection and MIMO processing at the receivers. Several MGM schemes have been implemented based on conventional MMFs or FMFs, in which all the intra-group modes need to be detected simultaneously at the receiver to avoid the mode partition noise resulting from the random intra-group mode crosstalk [12][13][14]. However, as the number of intra-group modes in graded-index (GI) MMFs linearly increases with the MG order [as shown in Fig.…”

An orbital-angular-momentum (OAM) mode-group multiplexing (MGM) scheme using high-order mode groups (MGs) in a graded-index ring-core fiber (GIRCF) is proposed, in which a receive-diversity architecture is designed for each MG to suppress the mode partition noise resulting from random intra-group mode crosstalk. The signal-to-noise ratio (SNR) of the received signals is further improved by a simple maximal ratio combining (MRC) technique on the receiver side to efficiently take advantage of the diversity gain of the receiver. Intensity-modulated direct-detection (IM-DD) systems transmitting three OAM mode groups with total 100-Gb/s discrete multi-tone (DMT) signals over a 1-km GIRCF and two OAM mode groups with total 40-Gb/s DMT signals over an 18.4-km GIRCF are experimentally demonstrated, respectively, to confirm the feasibility of our proposed OAM-MGM scheme.
