Modulation of signals in optical systems
A method for modulating signals in an optical system comprises generating a digital electrical input signal, dividing the signal into two parts, passing one part of the signal to an electrical inverter, converting the un-inverted and inverted electrical signals to un-inverted and inverted optical si...
