ABSTRACT:
An integrated cascaded optical phase modulator for providing linearized complementary modulated light output signals consists of the successive cascade of a first phase modulator stage, first fixed optical coupler, second phase modulator stage, and second fixed optical coupler Rf modulating signals applied to each phase modulator stage are adjusted in amplitude, for compensating for errors in the coupling angles of the first and second optical couplers. The levels of DC bias voltages applied to each phase modulator stage are adjusted for compensating for asymmetric phase modulation.
