1. An optical module, comprising:
- a circuit board having an upper surface in which an electronic element is mounted and an edge having an opening inwardly formed;
a glass rod inserted into the opening of the circuit board;
an optical waveguide array in which a plurality of optical waveguides are formed;
an optical element in which an optical signal that is transmitted and received from and to the optical waveguide is input and that is mounted at a lower surface of the circuit board; and
a connection member that connects the optical element and the electronic element,wherein the glass rod has a connection portion of a curved shape between the upper surface and the lower surface,wherein the connection member is formed on the connection portion,wherein the connection member comprises;
a transmission line, an entirety of the transmission line is curvedly formed along the curved shape of the connection portion of the glass rod; and
a wire bonding unit that connects the electronic element and the optical element at both ends of the transmission line, the wire bonding unit is directly connected to both ends of the transmission line, andwherein the transmission line is directly formed in a pattern in the glass rod.
