Near-field optical head and method for manufacturing the same |
摘要 |
<p>A near-field optical head includes an optical waveguide (2501) formed from a clad (2502), a core (2503) and an optical element (2504), which co-operates with the clad to clamp the core. The clad (2502) has at least one inverted conical or pyramidal hole (2502a) formed through it, the apex of which is made as a very small aperture (2502b) for producing near-field light. A reflection film (2505) is provided on one end surface of the optical waveguide (2501). Also provided is a method for manufacturing such a near-field optical head.</p> |
