ABSTRACT:
An apparatus for amplifying the optical power ratio includes first and second input electro-absorption modulators coupled together in series that each receive an optical input beam. First and second output electro-absorption modulators are coupled together in series and each generate an optical output beam. A voltage amplifier electrically couples a first node located between the first and second input modulators to a second node located between the first and second output modulators. In operation, the power ratio of the output beams is a function of the power ratio of the input beams.
