Abstract
A method involving: providing an optical waveguide made of a semiconductor material and having a region that is doped by a deep level impurity which creates deep level states in a bandgap in the semiconductor material, the deep level states characterized by an occupancy; passing an optical signal through the optical waveguide and between the region doped by the deep level impurity; and modulating the occupancy of the deep level states to thereby modulate the optical signal.
