Abstract
In some implementations, a VCSEL includes a first cap layer and a second cap layer. The first cap layer includes a semiconductor material and is disposed over a confinement aperture of the VCSEL. The second cap layer includes a dielectric material and is disposed over the confinement aperture of the VCSEL. A polarization filter structure is formed in the first cap layer. A mode filter structure is formed in the second cap layer.
