Abstract
In external modulation, a modulated light signal is shaped to decrease pulse transition times resulting in less chirp. Accordingly, the modulated signal travels greater distances with less pulse distortion over an optical medium. For an integrated-type of external modulator, chirp is reduced further by using a laser modulator coupled to multiple complementary output ports.
