1. A light-emitting element with porous light-emitting layers, comprising:

  • a substrate;

    a first conductive cladding layer;

    a second conductive cladding layer; and

    at least one porous light-emitting layer formed between the first conductive cladding layer and the second conductive cladding layer, the porous light-emitting layer having an upper barrier layer, a lower barrier layer and a carrier trap layer, the carrier trap layer positioned between the upper barrier layer and the lower barrier layer, the carrier trap layer having a plurality of chevron structures for defining a plurality of valley shaped structures, the carrier trap layer being an indium-containing nitride structure, the energy band gap of the carrier trap layer being less than that of the upper barrier layer and the lower barrier layer.
