摘要： A slider including a magnetic head part, an optical waveguide, and a near field element is fixed by first and second adhesives to a submount on which a semiconductor laser and a mirror are mounted, the mirror being placed at one end of the semiconductor laser in a resonance direction thereof and reflecting a laser in a direction intersecting with the resonance direction. At this time, at least parts of the first and second adhesives are applied to a position opposed to the semiconductor laser with an intermediation of the submount. The first adhesive having a higher Young's modulus than that of the second adhesive is applied onto an inflow end side of the slider including a solder connection portion, the second adhesive being applied onto an outflow end side of the slider.

摘要： In a thermally assisted magnetic recording head having a light source and a waveguide to lead a laser beam radiated from the light source to a front end of the magnetic head, while blocking an adverse effect of heat generated in the light source and securing a good floating characteristic, the light source and the magnetic head are optically coupled with high efficiency and the magnetic head itself is reduced in size. This invention provides a reflection mirror that is formed of a part or whole of one inclined end surface of the semiconductor laser mounted on the first submount. Near one end surface of the slider is provided the optical waveguide that pierces through the slider in a direction of the thickness thereof. The slider is mounted on the second submount and the positions of the first submount and the second submount are adjusted to practically align the light axis of the beam emitted from the mirror with the light axis of the optical waveguide, thereby realizing a novel thermally assisted magnetic recording head.

摘要： An optical integrated circuit having optical devices is fabricated. These optical devices must be biased in the mutually opposite directions. If such an optical integrated circuit is fabricated using a conductive semiconductor substrate as conventionally, it is not possible to drive the devices by a single power supply since the substrate side is shared as a common polarity by the devices. The present invention realizes a structure where both anode and cathode of each device can be isolated electrically by conventional process technology and provides an optical integrated circuit which can be driven by a single power supply.An optical integrated circuit is formed on a semi-insulative or insulative substrate. A high resistivity region which extends at least from the active layer to the substrate and includes part of an optical waveguide between the devices is formed so as to electrically isolate the anode and cathode of each integrated device from the other device.
