Picosecond switching induced by saturable absorption in a nonlinear directional coupler

Fluence-induced changes in absorption of a semiconductor-doped-glass directional coupler have resulted in nonlinear optical switching on a picosecond time scale. The functional dependence on the incident fluence confirms that the switching is dominated by absorption saturation.
