Coupler for optical communication system |
摘要 |
A coupler for coupling the end of an optical signal transmission line comprising at least one optical waveguide, to a solidstate converter device such as a light emitting diode or a photosensitive diode according to the case, the converter device presenting a refractive index N3 higher than the refractive index N1 of the optical waveguide. The coupler comprises a transparent matching medium having at least a refractive index N4 of value intermediate between the values N1 and N3 and forming a thin parallel faced plate whose maximum thickness is determined on the basis of the numerical aperture of the guide.
