PCT No. PCT/GB87/00250 Sec. 371 Date Jan. 28, 1988 Sec. 102(e) Date Jan. 28, 1988 PCT Filed Apr. 14, 1987 PCT Pub. No. WO87/06411 PCT Pub. Date Oct. 22, 1987.A system for optically coupling components of one or more integrated circuits comprising a light source, means for focussing the light onto a modulatable electro-optic material located on or in a substrate, the electro-optic material being disposed above and partially covering a reflective coating. The focussing means is arranged relative to the covered and uncovered portions of the reflective coating and relative to a detector element on or in the substrate whereby reflected modulated light from the electro-optic material and reflected unmodulated light from the uncovered portion of the reflective coating are superimposed to create an amplitude modulated beam for focussing on the detector element.
