Abstract :
In this paper, we present mode-locked operation of a monolithic 20GHz integrated extended cavity ring laser. The 4mm-long laser ring cavity incorporates a 750μm-long optical amplifier section (SOA), a separate 40μm long saturable absorber (SA) section, passive waveguide sections (shallow and deep etch) and a passive MMI type 50% output coupler. The active sections contain a four quantum well active layer. The output waveguides are tilted under an angle of 7° to minimize back reflections into the device. Device fabrication has been carried out in the JePPIX technology platform.
