Abstract: A light-emitting device includes a photoluminescent layer and a light-transmissive layer. At least one of the photoluminescent layer and the light-transmissive layer has a submicron structure including at least two periodic structures. Light emitted from the photoluminescent layer includes first light having a wavelength λa in air and second light having a wavelength λb in air. The at least two periodic structures include a first periodic structure having a first period pa that satisfies λa/nwav-a

Abstract: A light-emitting apparatus includes; a light-emitting device including a photoluminescent layer that receives excitation light and emits light including first light having a wavelength λa in air, and a light-transmissive layer located on or near the photoluminescent layer; and an optical fiber that receives the light from the photoluminescent layer at one end of the optical fiber and emits the received light from the other end thereof. A surface structure is defined on at least one of the photoluminescent layer and the light-transmissive layer, and the surface structure has projections or recesses or both and limits a directional angle of the first light having the wavelength λa in air.
