Abstract
Abstract An optical coupling arrangement for coupling the data modulated light beam from the output of one optical device to the input of a further optical device which permits transmission of the desired band width but substantially avoids mode mismatching. The desired coupling is achieved by providing a pair of reflective surfaces, i.e. mirrors, which face one another and are spaced with respect to one another so that they define an optical resonator for the wavelength of the light to be transmitted in the coupling medium therebetween, connecting the output of one of the optical devices to a light permeable aperture in one of the reflective surfaces and connecting the input of the other optical device to a light permeable aperture in the other of the reflective surfaces.
