Can complex 3D subwavelength-sized structures molded in plastic optical ROM media be interrogated by a diffraction-limited focused spot for the retrieval of multilevel information? Finite-difference time-domain (FDTD) methods are used to examine the reflected intensity fields from such structures. The results presented show that such information retrieval is possible.
