K-series approximation of vectorial optical fields for designing diffractive optical elements with subwavelength feature sizes
I-Lin Ho
Diffractive optical elements (DOEs) are widely applied as compact solutions for desired light manipulations via wavefront shaping. Recent advanced chip applications further require…

Study of wide-spectrum and high-resolution diffraction optical elements by stacks of binary phase gratings
I-Lin Ho, Wang-Yang Li
This work theoretically investigates wide-spectrum and high-resolution diffraction optical elements (DOE) that are made of stacks of low-resolution binary phase gratings, whereby t…
