    摘要: A magnetic write head having a main magnetic write pole and a magnetic sub-pole that are configured to maximize magnetic performance. The main magnetic write pole has a flared portion located near the air bearing surface and a non-flared portion removed from the air bearing surface. A magnetic sub-pole is formed adjacent to the main magnetic write pole and terminates at a front endpoint that is recessed from the air bearing surface but is closer to the air bearing surface than the non-flared portion.

    摘要: The optical module includes an optical device mounting substrate 1 and an optical multiplexer/demultiplexer 2. One laser diode and at least one photodetector, which are positioned in the same plane, are mounted on the optical device mounting substrate 1. The optical multiplexer/demultiplexer is prepared by mounting a wavelength-selective filter and a mirror on the front and back surfaces of a transparent substrate. The optical device mounting substrate and the optical multiplexer/demultiplexer are mounted in a package 3 in such a manner that the optical device mounting surface and the filter surface are not parallel to each other. The optical module also includes a first lens, which is positioned near the laser diode or monolithically integrated with the laser diode, and a second lens, which converges light coming out of the optical multiplexer/demultiplexer toward an optical fiber.

    摘要: A semiconductor laser device includes a semiconductor substrate, a first cladding region on one side of the semiconductor substrate, an active layer region, and a second cladding region disposed on an opposite side of the semiconductor substrate. The active layer region is disposed between the semiconductor substrate and the second cladding region. A first semiconductor region is provided on either side of the active layer region in parallel with a traveling direction of light in the active layer region and has an electric resistance higher than that of the active layer region and a refractive index higher than that of the semiconductor substrate. An insulative or semi-insulative second semiconductor region is formed between the first semiconductor region and part of the second cladding region. A first electrode and a second electrode are provided for injecting a current into the active layer region.
