Independent and sequential writing-erasure of one cavity soliton while keeping the neighboring cavity soliton unchanged (a,b,c). The black trace corresponds to the incoming localized excitation pulse, and the middle (upper resp.) trace, green (red resp.) online, corresponds to the leftmost (rightmost resp.) cavity soliton. The zero intensity levels of the upper and middle traces (dashed lines) have been artificially offset by 100 and 50, respectively for clarity. An averaged image of the two-cavity solitons considered is shown in (d). After [73].
