Abstract
An optical semiconductor package has a base material that includes a principal surface, an optical semiconductor element that is located on the principal surface of the base material to project or receive light, and an optical transparency sealing layer that seals the optical semiconductor element while covering the principal surface of the base material. An air gap having a shape surrounding an optical axis of the optical semiconductor element is provided in the optical transparency sealing layer such that the light is reflected by an interface of a portion corresponding to an inner circumferential surface of the air gap in an interface formed by the air gap and the optical transparency sealing layer.
