Abstract :
The dynamic performance of an integrated multiwavelength light source based on a UV written waveguide grating external cavity laser is described for the first time. It has 4 wavelength channels, each of which is successfully modulated at 2.5 Gb/s. We have described the first demonstration of an integrated multiwavelength light source based on the hybrid integration of laser diodes with UV written Bragg gratings in silica waveguides on silicon. 4 channels were successfully modulated at 2.5 Gb/s. This light source will play an important role in WDM transmission and access network systems
