Abstract :
Temporal and spectral characteristics of single-longitudinal-mode short-coupled cavity (SCC) InGaAsP injection lasers in the 1.5 ¿m wavelength range under high-frequency (1¿7.5 GHz) direct modulation are reported. The effects of modulation on the spectral broadening and chirping of the longitudinal modes were studied. Predominantly single-longitudinal-mode operation under direct high-frequency modulation was achieved by compromising the on/off ratio.
