We propose a fabrication technique for harmonic Fresnel lenses by combining grayscale lithography and soft nanoimprinting.
We propose an alternative method for fabricating DOEs without RIE lag and with improved surface smoothness.
We explore the use of hexagonal grids as a new grid structure for DOE design and fabrication.
We propose a new way to fabricate multi-level DOEs by directly growing an optically transparent material on a glass substrate.
We propose an additive lithographic fabrication process to realize simultaneous micrometer and millimeter features.
We propose an etch-free additive lithographic fabriction method for versatile reflective and transmissive DOEs.
