摘要： A light absorbing layer, and a window layer formed thereon constitutes a first conduction-type semiconductor layer. In a part of this first conduction-type semiconductor layer there is provided a second conduction-type region extending to the light absorbing layer through the window layer. A part of the window layer around the second conduction region is selectively removed. Consequently even when light intended to enter a light detecting region is incident outside of the light detecting region, most of the carriers generated there are recombined at a surface level of the light absorbing layer before diffusing in a depletion layer. This light detecting device therefor does not substantially detect sensitivity to light incident outside the light detecting region.

摘要： This invention relates to a light detecting device comprising a first conduction-type semiconductor substrate, a first conduction-type semiconductor crystal layer formed on the surface of the substrate, and a second conduction-type first region formed in the semiconductor crystal layer. The first region is surrounded by a second conduction-type second region. On the surface of the semiconductor crystal layer, an electrode is formed on the first region, and a reflection preventing layer is formed on that part of the first region inside the electrode, and a device protecting film is formed on that part of the first region outside the electrode. On the semiconductor crystal layer, a metal film is formed in contact both with the semiconductor crystal layer and with the second region. This structure enables the second region to capture unnecessary charges and further to recombine and extinguish them.

摘要： A resin sleeve is used as an optical connection sleeve 1 for optically connecting an optical fiber 41 with an optical component. A ferrule fixing surface 21 provided on an inner peripheral surface of a ferrule insertion portion 2 of the sleeve 1 is formed to have a multifaceted shape in which a cross section thereof on a plane vertical to an optical axis A thereof has a hexagonal shape. A ferrule 40 can be positioned and fixed accurately by a tight fit utilizing elastic deformation of resin. An outer peripheral surface of the ferrule 40 and the ferrule fixing surface 21 come into line contact with each other, and thus detachability of the ferrule 40 is enhanced. Therefore, an optical fiber ferrule can be held accurately, and the optical connection sleeve having a satisfactory detachability, an optical module using the same and an optical communication module are realized.

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： An optical part 25, which is used to be placed at an end face of an optical fiber, is constituted by a single light-transmitting material transparent to light transmitted through the optical fiber, and comprises an optical fiber contacting face 30 disposed in contact with the end face of the optical fiber, and an light emitting face 33 tilted with respect to a cross section perpendicular to the axis of the optical fiber. Since the light emitting face 33 is formed with an inclination, such an optical part 25 restrains reflected light occurring at the optical fiber end face from going back to the optical fiber. Also, since the optical part 25 is constituted by a single light-transmitting material, its configuration is simple, and the length can be shortened in the optical axis direction.

摘要： A low doped semiconductive layer is formed on a semiconductor substrate of a highly doped first conductivity type, and a first region of a highly doped second conductivity type is selectively formed at a portion of the semiconductive layer. In a top-incidence type photo-sensing device having a pn junction area of the above structure as a photo-sensing region, the first region is surrounded by a second region of the second conductivity type formed at a portion of the semiconductor layer. The second region has the same or a larger depth as that of the first region. Thus, even if light is directed to the outside of the photo-sensing region, extra charges generated therein are absorbed by the second region and the flow of extra charges into the photo-sensing region is prevented.
