Abstract
A light emitting device includes a substrate and an adhesive layer on the substrate. At least two multi-layer epitaxial structures are on the substrate. Each structure sequentially includes an upper cladding layer, an active layer, a lower cladding layer, an ohmic contact epitaxial layer, and a first ohmic contact electrode adhered to the substrate by the adhesive layer. A second ohmic contact electrode is on the lower cladding layer. A channel divides the active layer into two portions. A first electrode is on the lower cladding layer corresponding to a first portion of the active layer. A second electrode is on the second ohmic contact electrode corresponding to a second portion of the active layer. A connection layer is formed in the structure so as to couple the first electrode with the first ohmic contact electrode. A dielectric layer is between these two structures. A conductive line couples the electrodes of these two structures.
