    摘要： An optical switch has a semiconductor waveguide region (2) formed on a substrate (1), with a cladding region (3) on a projection of the waveguide region (2). By controlling the fields applied to electrodes (4, 5, 6) on the substrate (1), the waveguide region (2), and the cladding region (3), the injection and extraction of carriers into and from the waveguide region can be controlled. It is found that the carriers can be removed rapidly through the electrodes (4, 5, 6) and this causes the switch to turn off very rapidly.
