The introduction of patterned current fronts that modulate the transition between directly modulated optical bits allows for a strong reduction of the optical chirp in a single-mode semiconductor laser, as shown in the numerical integration of a standard model. Hence, optical transmission of information over much longer distances without signal deterioration and a substantial increase in data transmission speed are possible. © 2001 American Institute of Physics.
