摘要： A near-field light generating device includes: a waveguide; a buffer layer disposed on the top surface of the waveguide; an adhesion layer that is formed by incompletely oxidizing a metal layer and disposed on the buffer layer; and a near-field light generating element disposed on the adhesion layer. The adhesion layer has a resistance-area product higher than that of the metal layer unoxidized and lower than that of a layer that is formed by completely oxidizing the metal layer. A layered structure consisting of the buffer layer, the adhesion layer and the near-field light generating element has a peel-test adhesive strength higher than that of a layered structure consisting of the buffer layer and the near-field light generating element.
摘要翻译：近场光产生装置包括：波导管; 设置在所述波导的顶面上的缓冲层; 通过不完全氧化金属层而形成并设置在缓冲层上的粘附层; 以及设置在粘附层上的近场光产生元件。粘合层的电阻面积比未氧化的金属层的电阻面积乘积低于通过完全氧化金属层而形成的层的电阻率积。由缓冲层，粘附层和近场光产生元件组成的分层结构的剥离测试粘合强度高于由缓冲层和近场光产生元件组成的层状结构的剥离测试粘合强度。

摘要： An optical waveguide of the invention includes a core that is a waveguide through which light propagates; and a cladding that surrounds the core. The core has a plate shape and includes a wide core base part onto which the light is incident, a taper part that is connected to the core base part and of which a width is gradually tapered along a propagation direction, and a narrow front end core part that is connected to the taper part and that extends along the propagation direction. A grating is provided on one of planar surfaces of the wide core base part, the grating is formed by engraving a number of concave grooves having a rectangular cross section on the planar surface along a width direction thereof, the grating is formed to be optically coupled with laser light that is incident perpendicularly onto the grating formation surface, a frequency (grating pitch: pitch of the concave grooves) of the grating is smaller than a wavelength (defined as a wavelength in the cladding) of the perpendicularly incident laser light, and a groove depth H1 of the grating is formed with respect to a thickness H2 of the core base part so that a relationship H1=(0.33 to 0.67)×H2 is satisfied.

摘要： A thermally assisted magnetic recording head includes a magnetic recording element part for writing, a main waveguide for assistance for receiving light, and a dummy waveguide component part provided in parallel to the main waveguide. The dummy waveguide component part includes a pair of waveguides having the same shape and dimensions including a first waveguide and a second waveguide that receive light from a back end surface opposite to an air bearing surface and guides the light toward the air bearing surface, and light emitting ends of the first waveguide and the second waveguide facing towards the air bearing surface have no shielding material, and are in a free condition so that the light intensity from the light emitting ends can be measured.
