Enhanced Carrier Confinement and Mode Discrimination for Laterally-Coupled DFB Lasers

Reducing carrier leakage is the key to obtain laterally coupled distributed feedback (DFB) lasers with high injection efficiency. We proposed a device structure with slots fabricated between the ridge and gratings to form a good confinement on carriers. The incorporation of slots also makes the grat...
