Claim:
1. An optical package, comprising: a semiconductor chip, the semiconductor chip comprising a first surface on which a pad configured to transmit an electrical signal is arranged and a second surface opposite the first surface; a conductive bump electrically connected to the pad and protruding away from the first surface of the semiconductor chip; an optical element in the semiconductor chip configured to input and/or output an optical signal through the second surface of the semiconductor chip; a molding member extending on sides and the second surface of the semiconductor chip, wherein the molding member comprises a window that exposes a portion of the second surface of the semiconductor chip and overlaps the optical element when viewed from a plan perspective; and an optical fiber module configured to transmit an optical signal to the optical element through the second surface of the semiconductor chip, a portion of the optical fiber module being inserted in the window of the molding member, wherein the semiconductor chip further comprises a reflective layer on the first surface that is configured to reflect an optical signal toward the optical element, and wherein the optical element is between the optical fiber module and the reflective layer.
