Abstract
An optical coupling element is provided between a semiconductor transmitter, a semiconductor receiver and a lightwave guide. The optical coupling is effected through microoptics which are adjustable in a simple way. Such a coupling element is useful particularly as a subscriber's connection in an optical waveguide duplex or multiplex communication system and uses a reflective planar surface with a reflection which is responsive to the wavelength to pass light to the transmitted and reflected light to be received.
