Reconfigurable Multiwavelength Source Based on Electrooptic Phase Modulation of a Pulsed Laser

A reconfigurable multiwavelength source based on time-domain electrooptic phase modulation of a pulsed laser is proposed and experimentally demonstrated. The technique permits great reconfiguration in the spectrum allocation and wavelength separation. A tunable 5-GHz and 2.5-GHz frequency spacing from a 10-GHz mode-locked laser is experimentally demonstrated. A 5-GHz frequency shift is also demonstrated.
