Abstract

A hybrid, evanescently-coupled III-V/Silicon distributed feedback laser with an integrated monitor photodiode, based on adhesive divinyl siloxane-benzocyclobutene bonding and emitting at 1310 nm is presented. An output power of ~ 2.85 mW is obtained in continuous wave (CW) regime at 10 °C. The threshold current is 20 mA and a side mode suppression ratio of 45dB is demonstrated. Optical feedback is provided via corrugations on top of the silicon rib waveguide while a specially developed bonding procedure yields 40nm-thick adhesive bonding layers, enabling efficient evanescent coupling.
