The excitation process of short optical pulses in waveguides by use of prism couplers is studied with a fully dynamic model. A good coupling efficiency is obtained even for short pulses. Fast nonlinear behavior such as power limiting and optical switching is predicted with a response time much shorter than the buildup time of the waveguide coupler. This new result is due to the group-velocity matching between the guided and the pump fields.
