LIGHT COUPLING STRUCTURE, METHOD OF FORMING A LIGHT COUPLING STRUCTURE AND A MAGNETIC RECORDING HEAD

摘要

A light coupling structure, a method of manufacturing a memory cell, and a magnetic recording head are provided. The light coupling structure includes a light coupling layer having a cavity; a waveguide having a cladding layer and a core layer; wherein the cladding layer of the waveguide is disposed in the cavity of the light coupling layer and the core layer of the waveguide is disposed over the light coupling layer and the cladding layer of the waveguide; wherein the light coupling layer is configured to receive light from a light source and couple the received light into the core layer of the waveguide.
