Abstract: An optical waveguide platform and a method of manufacturing the same are disclosed. The optical waveguide platform comprises an optical waveguide having a lower clad layer, a patterned core layer and an upper clad layer which are laminated on one area of said substrate sequentially, a terrace formed by patterning said lower clad layer, on the other area of said substrate, a metal and a solder formed on said terrace and an optical device mounted on said terrace containing said metal and said solder. According to the present invention, the optical waveguide platform can be manufactured in a simple method without damaging the optical waveguide and the manufacturing cost thereof can be reduced.
