Abstract:
A fiber-optic transmitting component, comprising:a housing; a light-emitting device surrounded by said housing, said light-emitting device emitting a linearly polarized beam of radiation having a first polarization axis emerging from said housing in a main direction; an adjusting sleeve having a first end connected to said housing, a base plate disposed at said first end and formed with a central opening, and a second end remote from said first end, said adjusting sleeve extending between said first end and said second end in the main direction of the beam of radiation emerging from said housing, said second end of said adjusting sleeve for receiving and fixing an optical fiber such that the beam of radiation emerging from said housing is coupled into the optical fiber, said adjusting sleeve having an inner diameter, said central opening of said base plate having a diameter smaller than said inner diameter; and a polarization filter attached to said base plate such that it covers said central opening of said base plate, said polarization filter having a second polarization axis forming a non-zero angle relative to said first polarization axis, said non-zero angle being determined by a desired light density to be coupled to the optical fiber.
