Abstract:
1. A structure comprising: a first epitaxial structure comprising a first active region sandwiched between a first n-type region and a first p-type region, the first active region configured to emit light having a polarization ratio, defined as (|I a polarizer disposed in a path of light emitted by the first active region, wherein the polarizer is oriented to transmit light of a polarization of a majority of light emitted by the first active region; and a second epitaxial structure comprising a second active region sandwiched between a second n-type region and a second p-type region, the second active region configured to emit light having a polarization ratio of at least 50% when forward biased; wherein: the polarizer comprises a plurality of evenly spaced, parallel metal lines; the polarizer configured to serve as an electrical contact between the first and second epitaxial structures; the polarizer is disposed between the first epitaxial structure and the second epitaxial structure; and the polarizer is oriented to reflect light of a polarization of a majority of light emitted by the second active region.
