    摘要: A method of making a holographic light guide comprising, in sequence, a substrate, a light guiding layer and a holographic recording layer that partially replaces the light guiding layer is disclosed. The substrate is made of a first bismuth sillenite group substance. The light guiding layer is made of a second bismuth sillenite group substance that has a higher refractive index than the first bismuth sillenite group substance and absorbs little of the light being guided. The holographic recording layer is made of a third bismuth sillenite group substance that has a higher refractive index than the first bismuth sillenite group substance and has a degree of photosensitivity.

    摘要: An optical module includes a semiconductor optical device, an optical fiber, a ferrule, and a mounting component. The optical fiber is optically coupled to the semiconductor optical device. The ferrule holds the optical fiber. The mounting component includes a first support groove for supporting the ferrule and a second support groove for supporting the optical fiber. The semiconductor optical device is mounted on the mounting component. The first and second support grooves are sequentially arranged in a direction of a predetermined axis. The second support groove has one end and the other end. The depth of the second support groove decreases from the one end toward the other end. With such a structure, the optical module allows the optical fiber to be positioned with high accuracy onto the mounting component.

    摘要: Besides the central pn-junction and the central electrode, a PD chip has a peripheral pn-junction and a peripheral electrode which do not appear on the sides. The ends of the peripheral pn-junction are covered with a protection layer for preventing self-shortcircuit. A reverse bias is applied to the peripheral electrode for making a wide depletion layer beneath the peripheral pn-junction. Extra carriers generated by peripherally-incidence rays are fully absorbed by the peripheral depletion layer and annihilated by the reverse bias.

    摘要: A semiconductor photodetector comprising a photodiode chip, a header for mounting the chip, a receptacle, and a ferrule for holding an end of an optical fiber. The photodetector does without a lens. A dielectric layer covers a periphery of the photodiode chip for shielding it from incidence of extra light beams by reflecting or absorbing light. Omission of a lens reduces the costs of parts and assembly. Since no light beams enter the peripheral part of photodiode chip, no delayed photocurrent is produced. Reproduced signals are immune from deformation or delay of phase. The photodetector facilitates wide prevalence of optoelectronic communication.

    摘要: A semiconductor light source for transmitting light signals of digital or analog data having a laser diode and a photodiode for monitoring the output power of the laser diode. The driving current of the laser diode is adjusted by the photocurrent of the monitoring photodiode. The photodiode has a light receiving region at a center enclosed by an annular electrode and a light non-receiving region outside the annular electrode. If leak light beams entered the non-receiving region, delayed photocurrent is produced. The delayed photocurrent misleads the control of the laser diode. This invention provides a non-receiving region of the photodiode with a dielectric layer for reflecting or absorbing light beams in order to preventing the light beams from producing the delayed photocurrent.

    摘要: A magneto-optical converter utilizing the Faraday effect is disposed between the opposed ends of an iron core having a magnetic field extending therebetween. The magneto-optical converter is comprised of a body of material exhibiting the Faraday effect which is provided with a light receiving surface and a light exiting surface. A polarizer in the form of a polarizing beam splitter is located adjacent the light receiving surface whereby an incident beam of light perpendicular to the magnetic field will be deflected and polarized at right angles to the incident beam of light and directed into the receiving surface of the body of material. An analyzer comprised of a polarizing beam splitter is located adjacent the light exiting surface whereby the beam of light from the body of material will be deflected and polarized and exit the analyzer at right angles to the magnetic field. The receiving and exiting surfaces of the body material may be bevelled and optical rotators may be disposed intermediate the bevelled surfaces and the polarizer and the analyzer respectively.
