Abstract
An optic waveguide includes a buffer layer with an index n1, a strip with a high index n2 and a guiding layer with an index n3. The refraction indices correspond to the relationship: n2>n3>n1. The thickness of the strip is chosen to be very small so as to induce no optic losses. The device can be applied to the making of optic and electrooptical components.
