Abstract
The frequency chirping of directly modulated semiconductor lasers limits the transmission bandwidth of single-mode optical fiber communication systems. To eliminate this problem, external modulation has been introduced as an alternative to direct modulation of the laser.1,2 However, due to the phase modulation associated with refractive-index changes inside an intensity modulator, the chirping problem can still exist for modulators using either index or absorption effects.3
