Abstract

Several proposals have been made to produce heads for optical storage drives using integrated optics.¹ They have the advantages of being small, robust, and simpler to fabricate than heads made of conventional optical components. One of the key issues in optical heads is the process of coupling light from the integrated head to the optical disk and back again. It is important that this process be very efficient and that it not distort the wavefront or beam polarization.
