The unusual electromagnetic responses of nanostructured metasurfaces endow them with
an ability to manipulate the four fundamental properties (amplitude, phase, polarization, and …

Photopolymers are very interesting as optically sensitive recording media due to the fact that
they are inexpensive, self‐processing materials with the ability to capture low‐loss, high …

We report a study of the determination of polymer cross‐linking, namely the degree of
conversion and refractive index of the microstructures created by two‐photon polymerization …

There are distinct advantages to designing polymer systems that afford two distinct sets of
material properties–an intermediate polymer that would enable optimum handling and …

Photopolymer materials have received a great deal of attention because they are
inexpensive, self-processing materials that are extremely versatile, offering many …

We fabricate 100% fill factor microlens arrays (MLAs) using femtosecond laser direct writing.
The array consists of periodical hexagonal plano-convex microlens units with a diameter of …

In this work, we present the fabrication of nanoporous polymer-infiltrated nanoparticle films
(PINFs) with either uniform or graded porosity based on undersaturated capillary rise …

Metasurfaces have shown unprecedented capabilities in the manipulation of the light's
wavefront at subwavelength scale, enabling compact functional devices that can outperform …

In this review, it is argued that soft mass migrations, driven and guided by spatially controlled
photopolymerization and photochromic isomerization (also called directional plastic …

Optical imaging systems have greatly extended human visual capabilities, enabling the
observation and understanding of diverse phenomena. Imaging technologies span a broad …
