A Mach-Zehnder modulator (MZM) is horizontally integrated with a VCSEL. The horizontally-integrated MZM overcomes wavelength dependence problems of horizontally-integrated EA modulators and yet has the same advantages as the horizontally-integrated EA modulators in terms of overcoming ER and modulation range problems associated with vertically-integrated EA and EO modulators. By overcoming the problems by the existing integrated modulators, the operation speed of the VCSEL is increased and a modulation signal range is extended to allow a wider range of modulation signals and modulation schemes, including large-signal digital modulation schemes. |
