Abstract :
We have measured the frequency chirp characteristics of single-longitudinal-mode semiconductor lasers operating at 1.5 ¿m wavelength and subject to large signal amplitude modulation in the 50 to 800 MHz range. Measurements on cleaved-coupled-cavity (C3) and GRIN-rod external cavity lasers show that the wavelength chirp is large enough to cause a penalty in ultra-high-bit-rate long-haul optical-fibre systems.
