Abstract

The present embodiments provide apparatuses and methods for use in optically communicating information and/or data, including modulating optical signals by applying a first voltage across a first birefringent optical element (410), applying a second voltage across a second birefringent optical element (412), and modulating a frequency of the optical signal by adjusting at least one of the first and second voltage potentials and producing a change in a sum voltage (V+) that is proportional to the sum of the first and second voltage potentials. The present embodiments can further modulate an amplitude of the optical signal by adjusting at least one of the first and second voltage potentials and producing a change in a voltage difference (V-) that is proportional to the difference between the first and second voltage potentials as the optical signal passes through the first and second elements.
