Abstract
A light-emitting device according to an embodiment of the present disclosure includes a laminate. The laminate includes an active layer, a first semiconductor layer, and a second semiconductor layer. The first semiconductor layer and the second semiconductor layer sandwich the active layer in between. The light-emitting device further includes a current confining layer, a concave-shaped first reflecting mirror provided on side of the first semiconductor layer, and a second reflecting mirror provided on side of the second semiconductor layer. The current confining layer has an opening. The first reflecting mirror and the second reflecting mirror sandwich the laminate and the opening in between. The light-emitting device further includes a first reflecting layer and a phosphor layer. The first reflecting layer is disposed at a position opposed to the first reflecting mirror with a predetermined gap in between. The phosphor layer is disposed between the first reflecting mirror and the first reflecting layer, and performs wavelength conversion on light leaking from the first reflecting mirror.
