  • VERTICAL-CAVITY SURFACE-EMITTING LASER THAT PROVIDES POLARIZATION MODE CONTROL
    Publication number: 20250174965
    Abstract: In some implementations, a vertical-cavity surface-emitting laser (VCSEL) includes a confinement layer and a polarization mode filter. The confinement layer defines a confinement aperture. The confinement aperture is asymmetrical with respect to at least one axis of the confinement aperture. The polarization mode filter includes a grating. The confinement aperture and the polarization mode filter are configured to control a quantity of optical modes supported by the VCSEL and to lock a polarization of each optical mode supported by the VCSEL.
