AMORPHOUS SILICON ALLOY BASED INTEGRATED SPOT-SIZE CONVERTER

摘要

A photonic device (10) suitable for being optically coupled to at least one optical fiber having a first spot-size, the device including: at least one photonic component (30-50); and, a graded index lens (60) optically coupled between the at least one photonic component and the at least one optical fiber; wherein, the graded index lens is adapted to convert optical transmissions from the at least one photonic component to the first spot size. In one embodiment the graded index lens comprises an amorphous silicon based alooy material.
