英文摘要	PURPOSE:To decrease the optical loss of the junctures of optical waveguides which are provided on the same substrate by plural times of crystal growth and have different functions by cutting said junctures so that the waveguides are opposed to each other and paralleled in the thickness direction. CONSTITUTION:After a grown film 2 including the optical waveguides 5 is provided on the GaAs substrate 1, the boundary 7 with the film 3 is etched to cut the film so that the optical waveguides 5 and 5' are opposed to each other and are paralleled with each other in the thickness direction. A spacing 7 is set at =1 Kinds selected from the group consisting of amorphous SiO2, amorphous SiOx(0
