Abstract :
A chirping suppression scheme is proposed and demonstrated using a modified DFB-DC-PBH LD. This scheme is effective both for sinusoidal modulation and for pulse modulation. The chirping is suppressed to one tenth in 100 MHz sinusoidal modulation and one fifth in 2 Gbit/s pulse modulation.
