ABSTRACT:
The thin film optical element comprises a substrate, a thin film light guide formed by ion injection into the surface of the substrate, an optical functional part formed in a part of the light guide for varying the refractive index thereof by an external effect to modulate or deflect the guided wave, and an optical connector part formed at the end of the light guide for guiding the light or from the end face of said light guide, by differentiating the distribution of ion distribution between the optical connector part and the optical functional part.
