Optical E-field modulation using a directly driven laser

摘要

A method of synthesizing a modulated optical signal using a laser cascaded with an amplitude modulator. A phase drive signal VF(t) is derived for driving the laser to generate an optical carrier signal with a desired phase &phgr;(t). An amplitude drive signal VS(t) is then derived for driving the amplitude modulator to impose a desired amplitude S(t) onto the optical carrier signal generated by the laser. The amplitude drive signal VS(t) is compensated for amplitude modulation of the optical carrier signal generated by the laser.
