Abstract :
Wavelength switching dynamics of widely tunable transmitters are particularly important in switching systems for wavelength-division-multiplexing applications. By using a time-resolved spectrum technique, the wavelength switching OD behavior of a sampled grating distributed Bragg reflector laser a CD has been successfully characterized. The switching transient and related physical effects have been linked and clarified for the first time.
