1. An optical conveyance device, comprising:
an optical waveguide;
a first diode formed across the optical waveguide, the first diode including a first doped region of a first dopant type along a first side of the optical waveguide and a second doped region of a second dopant type along a second side of the optical waveguide, the first diode establishing a first intrinsic electric field across the optical waveguide in a first direction;
a second diode formed across the optical waveguide, the second diode including a first doped region of the second dopant type along the first side of the optical waveguide and a second doped region of the first dopant type along the second side of the optical waveguide, the second diode establishing a second intrinsic electric field across the optical waveguide in a second direction that is opposite the first direction;
a first electrical conductor connected to both the first doped region of the first diode and the first doped region of the second diode; and
a second electrical conductor connected to both the second doped region of the first diode and the second doped region of the second diode.
