Definitions

  • the invention relates to an optical fiber coupler for coupling two optical fibers.
  • Optical fibers are used to transmit information over long distances. It is regularly desirable to be able to interrogate the information to be transmitted at certain locations, ie to decouple a small amount of light or to couple information onto the light guide.
  • the invention has for its object to provide a light guide coupler which is suitable for coupling out and coupling in light in a simple construction.
  • this object is achieved by a capillary which receives the bevelled ends of the end sections of two light guides and which, at the level of the abutting ends, are arranged opposite one another and are oriented toward the interface between the ends of the end sections.
  • both photoelectric elements are photodiodes, but one of the two photoelectric elements can also be a photodiode and the other an LED. In exceptional cases, both photoelectric elements are formed by LEDs.
  • the two beveled ends etc. are glued to one another with an optically transparent adhesive.
  • the two ends can be provided with a dielectric mirror layer, or else with a partially transparent metal mirror.
  • the capillary should consist of glass, preferably quartz glass, the end sections of the light guides being welded to the capillary.
  • the end sections of the light guide can also be glued to the capillary.
  • the invention is explained below with reference to a drawing.
  • the single figure shows a schematic representation of such a light guide coupler.
  • the light guide coupler consists of a body 28 which is provided with a bore 30.
  • a glass capillary 22 is inserted into this bore, the inside diameter of which is slightly larger than the outside diameter of the light guides 18, 20 to be connected to one another.
  • the end sections 14, 16 of the light guides 18, 20 are inserted into the glass capillary 22, the ends 10, 12 of the end sections 14, 16, which are chamfered at an angle of 45 degrees, lie closely against one another, if necessary using a transparent adhesive .
  • the light- conductors 18, 20 themselves are connected to the body 28 of the coupler by a melting or adhesive plug 32.
  • the body 28 has photoelectric elements 24, 26 arranged opposite one another at the level of the interfaces of the ends 10, 12 of the end sections 14, 16 of the light guides 18, 20. These photoelectric elements can be two photodiodes, two LEDs or one photodiode and one LED.
  • the outcoupled light reaches one of the photoelectric elements, depending on the direction of the light on the photoelectric element 24 or else the photoelectric element 26.
  • the light guide coupler proposed here makes it possible to determine the direction of the light (Very little light output is coupled out of the light guide for this task).
  • a light source can then be controlled so that the light power transported by the fiber becomes independent of its temperature, aging or other influences.
  • Another application is an optical sensor: light is coupled into the light guide 18, for example by means of LEDs, part of the light being coupled out via the photoelectric element in order to regulate the light intensity of the light source to a fixed value.
  • the light passes through the light guide 16 to a sensor head which, depending on the measured variable, reflects more or less light back into the fiber.
  • the detector 16 receives this reflected light, which is now a measure of the measured variable.
  • the advantage over other known light guide couplers is that the partially transparent mirror covers the entire fiber cross-section uniformly and is not influenced by random changes in the light distribution in the light guide (mode hopping).
