摘要： A distributed-feedback laser has a diffractive grating, an optical waveguide layer, and an active region. The optical waveguide layer has equivalent refractive indexes larger towards cavity end facets and smaller towards a device center portion along a cavity. The active region containing the optical waveguide layer has widths wider towards the cavity end facets and narrower towards the device center portion along the cavity. The optical waveguide layer has a uniform electric intensity distribution along the cavity to improve the linearity of current versus optical output characteristics. In another arrangement, the optical waveguide layer formed on the diffractive grating has in its compositions longer wavelengths towards the cavity end facets and shorter wavelengths towards the cavity center portion along the cavity, whereby the optical waveguide layer has a uniform optical intensity distribution along the cavity to improve the linearity of current versus optical output characteristics. The distributed-feedback laser provided is with improved analog modulation distortion characteristics.

摘要： A light control apparatus includes a part for splitting an input light entering the light control apparatus through an optical fiber, a photoelectric conversion part for converting a monitor light into an electrical signal, and a third part for controlling the opening and closing of an optical transmission path for a signal light based on the electrical signal. The light power of an output light is controlled by the opening and closing amount of the optical transmission path which is controlled depending on the amount of the electrical signal output in accordance with the level of the monitor light. A semiconductor photovoltaic device capable of performing photoelectric conversion without using an external power source is used as the photoelectric conversion part. An optical shutter using a micromachine, or an optical device such as absorption-type modulator or refractive index-type modulator is used as the third part.

摘要： A planar type heterostructure avalanche photodiode comprises first and second semiconductor layers having first and second forbidden energy gaps. The second forbidden energy gap is larger than the first forbidden energy gap. In the second semiconductor layer, the second forbidden energy gap is increased as a distance is increased from a hetero-interface between the first and second semiconductor layers, and a pn junction is provided. A cross sectional shape of the outer periphery of the pn junction is defined by a curvature dependent on the increase of the second forbidden energy gap.

摘要： A micro-electro-mechanical systems device includes a substrate, each of an electronic circuit, an etch stop layer, and a hinge base mounted on the substrate, and an electrode connected to the circuit. A hinge is mounted on the base and is made of a doped semiconductor. The hinge includes a vertical support that extends vertically from the base, and a horizontally-extending hinge tab contacts the vertical support. The device also includes a movable mirror and a mirror via that couples the mirror to the hinge tab. The mirror is electrostatically attracted to the electrode responsive to application of a voltage between the electrode and the mirror, and movement of the mirror changes a relative position between the hinge tab and the vertical support. A stopper is mounted on the substrate that mechanically stops the movement of the mirror before the mirror contacts the electrode or etch stop layer.

摘要： An avalanche photodiode having a semiconducting light absorbing layer and an overlying avalanche gain layer of wide band-gap. The usual heavily doped region is formed in the avalanche gain region to form an abrupt p-n junction. Two semiconducting guard rings are formed around the heavily doped region. The doping of both rings provide graded p-n junctions with the avalanche gain layer. The inner guard ring extends more deeply into the avalanche gain layer than either the outer ring or the heavily doped region.
