ABSTRACT:
This specification discloses an integrated optical circuit element comprising a substrate, a wave guide layer formed on the substrate and having a refractive index higher than that of the substrate, and a photocoupler which is a diffraction grating pattern formed in the wave guide layer and having the same refractive index as that of the substrate. The specification also discloses a method of making an integrated optical circuit element which comprises the steps of forming a mask of diffraction grating pattern on a substrate, forming a layer having a refractive index higher than that of the substrate in a portion of the substrate which is not covered by the mask, and removing the mask.
