Fig. 4: 5 channel MRL array characterization.

a Schematic of the MRL array. b MRL LIV measurements for left and right outputs. c Corresponding optical spectrum. d Measured optical spectra of non-volatile lasing states for all 5 MRLs with time duration data overlapped. e Close-up of non-volatile lasing states for each MRL. f Tracked peak wavelength of the various non-volatile states.
