A meta‐lens is an advanced flat optical device composed of artificial antennas. The
amplitude, phase, and polarization of incident light can be engineered to satisfy the …

Purpose To outline the refractive problems associated with presbyopia and to review the
basis and relative merits of currently‐available methods for their correction, with detailed …

Freeform optics has become the most prominent element of the optics industry. Advanced
freeform optical designs supplementary to ultra-precision manufacturing and metrology …

Flat optics, metasurfaces, metalenses, and related materials promise novel on-demand light
modulation within ultrathin layers at wavelength scale, enabling a plethora of next …

Freeform optics aims to expand the toolkit of optical elements by allowing for more complex
phase geometries beyond rotational symmetry. Complex, asymmetric curvatures are …

Today's Virtual Reality (VR) displays are dramatically better than the head-worn displays
offered 30 years ago, but today's displays remain nearly as bulky as their predecessors in …

Presbyopia is the failure of the eye lens to accommodate. The widely used presbyopia
correction method involves wearing bi/trifocal or progressive glasses, which limits the field of …

Much of our system design relies on basic properties of 4f systems, which we state here for
completeness. The interested reader is referred to Goodman's book for additional details. A …

We introduce a new open-source software package written in Python to design and model
micro optical elements, such as diffractive lenses, holograms, as well as other components …

The design, fabrication and characterization of a miniature adjustable-focus endoscope are
reported. Such an endoscope consists of a solid tunable lens for optical power tuning, two …
