Abstract :
Cross gain modulation between two different optical signals, inserted through separate ports to an active MMI, has been experimentally measured. The observed trend of modulation reduction by increase of modulated signal power matches previous simulation results. An associated XPM is expected and could be optimized to enable using the active MMI in all-optical switching.
