Vertical-Cavity Silicon-Integrated Laser with In-Plane Waveguide Emission at 850 nm
Artikel i vetenskaplig tidskrift, 2018

A continuous-wave electrically-pumped short-wavelength hybrid vertical-cavity silicon-integrated laser (VCSIL) with in-plane emission into a silicon nitride (SiN) waveguide is experimentally demonstrated. The coupling from the vertical cavity into the in-plane SiN waveguide is achieved by a weak grating on the SiN waveguide placed inside the cavity. The grating provides coupling, sets the polarization of the lasing output, and provides transverse mode control. A 5 mu m oxide-aperture diameter device with a threshold current of 1.1 mA produces 73 mu W single-sided waveguide-coupled optical output power at 2.6 mA bias current at a wavelength of 856 nm and a side-mode suppression ratio (SMSR) of 29 dB.
