Hybrid III–V/Si Distributed-Feedback Laser Based on Adhesive Bonding

摘要

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 ${sim}{rm 2.85}~{rm mW}$ is obtained in a continuous wave regime at 10 $^{circ}{rm C}$. The threshold current is 20 mA and a sidemode suppression ratio of 45 dB is demonstrated. Optical feedback is provided via corrugations on top of the silicon rib waveguide, while a specially developed bonding procedure yields 40-nm-thick adhesive bonding layers, enabling efficient evanescent coupling.
