The mounds are spaced by 212.78 nm, and have a FWHM of about 90 nm. While these results are quite new and still being explored, they already indicate that some of our earlier worries about the requirements for relative phase stabilization of the standing waves in each dimension are unfounded. It appears that when orthogonal linear polarizations are used for the two standing waves, the phase stabilization problems can be minimized. Over the next year we hope to explore ways to reduce the spot size of the 2-D structures, with the aim of eventually scanning the substrate during deposition, so that a pattern can be generated within each unit cell of the array. Optical Manipluation of Macroscopic Objects is the next section of this Report.
Introduction is the previous section.
