1310-nm Hybrid III–V/Si Fabry–Pérot Laser Based on Adhesive Bonding

Abstract

An evanescently coupled, hybrid III-V/Silicon Fabry-Pérot laser based on adhesive divinyl siloxane-benzocyclobutene (DVS-BCB) bonding is presented operating at 1310 nm. We obtain 5.2-mW output power in continuous-wave (CW) regime at 10 <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">°</sup> C with a threshold current density of 2.83 kA/cm <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> in an 800-μm -long device. A specially developed bonding procedure produces 50-nm-thick bonding layers, enabling the evanescent coupling.
