Abstract :
Two-photon-induced photocurrents in two different semiconductors were coherently controlled simultaneously via femtosecond pulse shaping. Due to their distinct two-photon-absorption spectral responses, their photocurrent yield ratio was maximized (1.20:1) or minimized (0.75:1) using an evolutionary algorithm.
