Near-field light generating device including near-field light generating element with edge part opposed to waveguide |
摘要 |
A near-field light generating device includes: a waveguide having a groove that opens in the top surface; a clad layer disposed on the top surface of the waveguide and having an opening that is contiguous to the groove; a near-field light generating element accommodated in the opening; and a buffer layer interposed between the near-field light generating element and each of the waveguide and the clad layer in the groove and the opening. The near-field light generating element includes: first and second side surfaces that decrease in distance from each other toward the groove; an edge part that connects the first and second side surfaces to each other and is opposed to the groove with the buffer layer therebetween; and a near-field light generating part that lies at one end of the edge part and generates near-field light.
