Abstract

Figure 1 illustrates an integrated optical system comprising a Luneburg lens 11 for a planar waveguide 12 which is supported on a suitable substrate 13. As shown in Figure 2, to permit the lens 11 to be formed through a vacuum deposition process or the like, a mask 14 having an iris-like aperture 15 with a diameter which increases or decreases as a function of time is used to mask the waveguide 12 while the lens 11 is being formed. The rate at which the diameter of the aperture 15 is increased or decreased determines the curvature of the lens 11.
