Abstract :
Simulations and experiments show that the tunneling current in a field emitter may be modulated by means of a laser. The steady-state response is calculated with Floquet methods, and the transient response is found by a numerical method that does not use absorbing boundary conditions or a split-operator formulation. The transient solutions show that the response is delayed by the semiclassical tunneling time, which is defined as the time for traversing the inverted barrier
