description The present invention relates to an optical device connected to an optical fiber transmission line, capable of receiving or transmitting/receiving a light signal, and a method for producing the same. The optical device of the present invention includes a substrate, at least one first groove formed on the substrate, an optical fiber placed in the first groove, and at least one second groove diagonally formed across the optical fiber. Furthermore, the optical device includes an optical member inserted in the second groove, having a surface which reflects or diffracts at least a part of light propagating through the optical fiber. A photodetector is placed at a position where light which is reflected or diffracted by the optical member is received. As a result, an miniaturized optical device having a low loss and high reliability can be provided at low cost.
