    摘要： An optical receiver is provided with an optical-signal-receiving section and a controlling section. The optical-signal-receiving section incorporates a photodetector. The photodetector has an APD. Through a passivation film, a photoconductor is placed on a portion of a surface of the APD which remains unoccupied by an optical-signal-receiving area of the APD. When this structure is employed, the signal for controlling the avalanche multiplication factor of the APD can be obtained from the photoconductor. Consequently, the signal can be obtained with a simple structure. Furthermore, the photoconductor has a good linearity of the output current even to a weak lightwave. As a result, the output current I for controlling the avalanche multiplication factor of the APD can be obtained with high accuracy.

    摘要： In an optical communications module comprising one or more dielectric substrates equipped with an optical transmitter section, an optical receiver section or an optical transceiver section, and a chassis encasing all of them, a metal part is formed on one side of at least one of the dielectric substrates such that the metal part constitutes the whole or a part of the exterior surface of the chassis so that the length of heat conduction from a dielectric substrate with heat-generating components installed thereon can be minimized so as to efficiently release heat through the metal part to outside, curbing a temperature increase within the chassis. Thus, the optical communications module can exhibit excellent performance.

    摘要： A jointing holder for an optical module for single-fiber bidirectional communication comprises a unitarily structured cylindrical body that has the following portions: (a) an optical fiber-fixing portion for securely holding an optical fiber for transmitting multiwavelength light bidirectionally, (b) a semiconductor laser-fixing portion for securely holding a semiconductor laser for emitting outgoing light λ1, (c) a photodiode-fixing portion for securely holding a photodiode for receiving incoming light λ2, (d) an optical path-forming space for optically coupling the optical fiber, the semiconductor laser, and the photodiode, and (e) in the optical path-forming space, an optical filter-fixing face for securely holding an optical filter for separating multiplexed wavelengths. The jointing holder enables the optical module to reduce the number of components, to be miniaturized, and to reduce the dimensional deviation at the time of the assembly, enabling high-precision assembly. An optical module for single-fiber bidirectional communication incorporates the jointing holder.

    摘要： A photodiode (PD chip) includes a substrate, an absorption layer, a p-n junction in the absorption layer, a passivation film for protecting the end of the p-n junction, a p-electrode, and an n-electrode. The passivation film is covered with a protective layer composed of an insulative resin and having a thickness larger than that of the passivation film such that the passivation film of the PD chip fixed to the Si wafer and hence the p-n junction are not damaged or contaminated when an Si wafer including a number of horizontally and vertically arranged chip units, each having a V-groove for fixing an optical fiber, a marker, and a metallized pattern, is diced. Thus, a low-cost optical receiver module that does not generate dark current can be produced.

    摘要： A light emitting device has a fiber stub component, a grating chip, a semiconductor optical amplifier, a photodiode, and a mount member. The fiber stub component is comprised of a ferrule and an optical fiber. The fiber stub component, grating chip, and semiconductor optical amplifier are mounted on the mount member and are optically coupled to each other. An optical cavity is comprised of a light reflecting surface of the semiconductor optical amplifier and a diffraction grating of the grating chip. In this configuration, the light emitting device can provide laser light of a desired wavelength, without use of a pigtail fiber. The light emitting device can be constructed in smaller size than those using the pigtail fiber.
