A weakly etched grating placed inside a vertical cavity surface emitting laser (VCSEL) cavity between the top and bottom DBR can couple out light into a waveguide connected to it. In this paper, the design of such an intra-cavity Silicon Nitride (SiN) grating for hybrid 850nm VCSELs integrated on a SiN waveguide platform will be presented. This design enables the integration of polarization stable, single mode and energy efficient VCSELs on a SiN photonic integrated circuits (PIC).
