Right after the first edition was published in 2007, I was invited to give seminars at a number
of universities in several countries. At that time, many people considered nanotechnology …

Flat lenses enable thinner, lighter, and simpler imaging systems. However, large-area and
high-NA flat lenses have been elusive due to computational and fabrication challenges …

We formulate and apply an efficient finite-difference time-domain algorithm to the analysis of
axially symmetric diffractive optical elements. We discuss aspects relating to minimizing …

It is generally assumed that correcting chromatic aberrations in imaging requires multiple
optical elements. Here, we show that by allowing the phase in the image plane to be a free …

We present a novel configuration for the implementation of subwavelength-based graded-
index devices. The proposed concept is based on the etching of one-dimensional …

A procedure for designing binary diffractive lenses by use of pulse-width-modulated
subwavelength features is discussed. The procedure is based on the combination of two …

We have developed a rigorous unidirectional method for designing finite-aperture diffractive
optical elements (DOE's) that employs a micro-genetic algorithm (? GA) for global …

Publisher Summary This chapter discusses the electromagnetic approach for the diffractive
optics. The chapter focuses on the domain of diffractive optics in which rigorous …

The boundary-element method is applied to the interaction of light with resonant metallic
nanoparticles. At a certain wavelength, excitation of a surface plasmon takes place, which …

We present a procedure for the characterization and the linearization of the photoresist
response to UV exposure for application to the gray-scale fabrication of diffractive optical …
