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： The module has a planar platform. A straight light guide is formed on the planar platform for guiding incoming light and outgoing light. A filter is interposed slantingly in the light guide for reflecting a part of light propagating in the light guide but for allowing the rest of the light to pass through. An LD or LED is mounted at an extension of the light guide for producing sending signal light and introducing the sending light into the light guide. A photodiode is mounted on the platform at a point on a path of the reflected light for sensing the incoming (receiving signal) light. Guide pins are fixed to the platform for attaching to and detaching from an optical connector having holes and an optical fiber. In the attached state, the end of the light guide of the module faces the end of the fiber in the connector.

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.
