There is. In this direct connection, it is necessary to precisely position and fix the optical fiber and the waveguide so that connection loss is reduced. Conventionally, in order to connect a planar waveguide type optical shunt directly to an optical fiber, two substrates both having the same thickness are prepared, and the waveguide is attached to one substrate and the optical fiber is attached to the other substrate. There is a method in which one end of the waveguide is arranged so that the output end face of the waveguide and one end face of the optical fiber are three-dimensionally butted against each other. However, in such a method, it is necessary to perform positioning in the 3Il11 directions, and there are problems in that there are many adjustment parameters and the adjustment is time-consuming, and moreover, the number of processing steps during manufacturing is also increased.
