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.

摘要： A magnetic field and electric current measuring device which uses bismuth silicon oxide (Bi.sub.12 SiO.sub.20) or bismuth germanium oxide (Bi.sub.12 GeO.sub.20) as a Faraday cell, and which is so adapted that polarized light which enters the cell is passed back and forth through the cell along the optic axis thereof to cancel any change in optical rotatory power ascribable to a variation in temperature. A magnetic field applied in the direction of the optic axis of the Faraday cell is measured based on the angle of rotation of the polarization plane of the polarized light. The surface of the Faraday cell may be coated with a transparent and electrically conductive thin film to eliminate the effects of external electric fields.

摘要： An optical receiver includes a PIN photodiode (PIN-PD) having an incident surface for receiving signal light, the PIN-PD transmitting a part of the signal light to the surface opposite to the incident surface, and an avalanche photodiode (APD) having an incident surface for receiving light transmitted through the PIN-PD. In the optical receiver, the ratio of the quantity of signal light detected by the PIN-PD and the ratio of the quantity of signal light detected by the APD are not affected by the polarization state of the signal light incident on the optical receiver, and accordingly the avalanche multiplication factor of the APD is suitably controlled on the basis of the signal light detected by the PIN-PD.

摘要： The present invention provides an optical receptacle having a superior insertion/extraction performance of the ferrule, and an optical sub-assembly applying the optical receptacle. The optical receptacle 1 includes a stub, a bush 4, a sleeve, and a sleeve cover. The stub having a lower portion covered by the bush, and an upper portion covered by the sleeve. The sleeve may be a rigid sleeve without any slit along the optical axis in its outer surface. The sleeve cover covers the sleeve and the bush. In the present optical receptacle, the bush is press-fitted into the gap formed between the stub and the sleeve cover. Accordingly, in addition to the application of the rigid sleeve, not only the sub is hard to slide out from the sleeve, but also the insertion/extraction performance of the ferrule to be inserted into the sleeve may be enhanced.
