초록
Provided is a vertical cavity surface emitting device. The surface emitting device includes a lower mirror layer emitting light having a long wavelength, an active layer providing an optical gain, a tunnel junction layer for confining a current, and an upper mirror layer, which are sequentially stacked on a compound semiconductor substrate, wherein a heat release layer is formed on side surfaces of at least one of the active layer, the tunnel junction layer and the upper mirror layer by using etching process, and the heat release layer has greater thermal conductivity than at least one of the active layer, the tunnel junction layer and the upper mirror layer.
