Abstract
Prism couplers are manufactured by disposing a prism (10) on an optically flat waveguide (11) such that the region therebetween is shaped for substantially optimum coupling of optical energy therebetween, and securing the prism to the waveguide without deformation of the waveguide. The prism may have a curved, for example part-cylindrical, base (FIG. 4) or be separated from the waveguide by appropriate spacers (FIGS. 5 or 6). The prism may be secured to the wavegudie by an optical epoxy compound.
