Abstract:
1. A device comprising: a semiconductor structure including a light emitting element that includes a light emitting layer disposed between an n-type region and a p-type region; and a contact electrically connected to one of the n-type region and the p-type region; a porous semiconductor region disposed between the contact and the light emitting element, wherein at least a portion of the pores is disposed between the contact and the light emitting element such that the n-type region, the p-type region, and the light emitting layer are on one side of the porous semiconductor region and the contact is on an opposite side of the porous semiconductor region; and wherein the semiconductor structure further comprises a first surface from which light extracted from the semiconductor structure is emitted, wherein the light emitting layer is disposed between the first surface and the porous region.
