The dynamics of a laser-driven nuclear wave packet on two coupled
potential energy surfaces with 2 degrees of freedom, modeling the
torsion of a 
- double bond interacting with a
vibrational mode, is studied by numerically solving the
time-dependent Schrödinger equation. An optimal control scheme
is employed to determine the laser field to realize a nano-switch
for cis-trans isomerization. The basic mechanism of the
controlled isomerization process as well as the features of the
optimal laser field and its dependence on the final time chosen
for the optimization are studied in detail.
