  Under the action of pump light, the conventional photonic crystal can be
turned into function photonic crystal. In the paper, we have designed optical
triode with one-dimensional function photonic crystal, and analyzed the effect
of period number, medium thickness and refractive index, incident angle, the
irradiation way and intensity of pump light on the optical triode
magnification. We obtain some valuable results, which shall help to optimal
design optical triode.
