Optical transmitter with quad-wire differential optical modulator and driver

An optical communication method, comprising:

• providing an electrical driver for generating a first differential pair of modulated drive signals and a second differential pair of modulated drive signals in response to a data stream, the first pair including first and second modulated electrical signals, the second pair including third and fourth modulated electrical signals;
• and
• configuring the electrical driver to apply the first, second, third, and fourth modulated electrical signals to an optical modulator including a first optical waveguide core and a second optical waveguide core, each of the first and second optical waveguide cores including a respective cathode side and a respective anode side joined to form a respective electrical diode,
• wherein each of the first, second, third, and fourth modulated electrical signals is applied to a respective one of the cathode side of the first optical waveguide core, the anode side of the first optical waveguide core, the cathode side of the second optical waveguide core, and the anode side of the second optical waveguide core.
