| 摘要 |
A system and method for VCSEL (vertical cavity surface emitting laser) polarization control is disclosed, including methods and apparatus comprising a component package ( 302, 304 ) having self-aligning features ( 316, 318 ), for indicating an alignment axis ( 320, 322 ), and an upper surface aperture ( 314 ) formed therein, a vertical cavity surface emitting laser device ( 308 ) having two emission polarizations ( 204 ) normal to one another, disposed within the component package and aligned such that each emission polarization is at about 45 degrees with respect to the alignment axis, and a linear polarization element ( 400, 402, 406 ) having a polarization direction ( 206 ), spanning the aperture and disposed such that the polarization direction is parallel to the alignment axis.
