Abstract :
Summary form only given. Instantaneous wavelength shifts in gain-switched short optical pulses from absorptive-grating gain-coupled (GC) DFB MQW lasers were measured and compared with those of Fabry-Perot lasers. The GC DFB laser showed characteristic wavelength shifts which resulted in much smaller chirping. Its mechanism is discussed
