ABSTRACT:
An optical coupling device has an optical wave-guide varied in difference in specific refractive index between a clad layer and a core layer, and the optical wave-guide serves as a convergent/divergent spot size converter; since reduction in cross section of the core layer is not required for the convergent/divergent spot size converter so that the optical coupling device is produced at a high production yield.
