Abstract
Dynamic response of a Q-modulated semiconductor laser is simulated based
on a rate equation model. Numerical results from both small-signal and
large-signal analyses show that the Q-modulation has much higher bandwidth
limit and smaller wavelength chirp than the direct modulation. It is shown
that a high-extinction-ratio, low-chirp modulation of 40 GHz RZ signal can
be achieved and the effects of various parameters on the Q-modulation are
discussed. In addition to high-speed communications, the Q-modulated laser
is particularly suitable for microwave carrier generation in
radio-over-fiber systems.
