Figure 9

Encoded (multiplexed) and measured (de-multiplexed) superposition weightings for multiplexed OAM modes sent through (a) N = 1, (b) N = 3 and (c) N = 5 integrated copies of the fan-out log-pol mode sorter. The similarity between the multiplexed and de-multiplexed detected modes are S = 0.791, S = 0.968 and S = 0.971 for the cases of N = 1, 3 and 5, respectively.
