3D photonic nanostructures with desirable functionalities in the visible light region and
beyond have been recently given vast and increasing attentions because of the ability to …

We demonstrate a tunable and omnidirectional microlaser in the form of a microdroplet of a
dye-doped, cholesteric liquid crystal in a carrier fluid. The cholesteric forms a Bragg-onion …

This article reviews the main results from the investigations performed on solid chiral
microparticles based on polymerized cholesteric droplets. The procedures of particles …

This work reports experimental investigation and numerical validation of millimeter-sized
Spherical Bragg Resonators (SBRs) fabricated using 3D printing technology. The frequency …

This work considers a perfect 3D omnidirectional photonic crystal; Spherical Bragg
Resonators (SBR), for lasing applications. We use the recursive transfer matrix method to …

Optically active nanostructures comprised of polymer multilayer microspheres surrounding
semiconductor quantum dots are studied. Comparative analysis of the optical properties of …

We report synthesis of polymer particles comprising layers with alternating high and low
refractive index. We used poly (heptafluorobutyl methacrylate) as the low refractive index …

In this book, the issues regarding the theory of optics and quantum optics of spherical
multilayered systems are studied. In such systems the spatial scale of layers becomes …

We studied the photon spectrum in coated microspheres with alternating quasiperiodic
layers having left-handed (LH) materials included. It is found that the band gap (spectral …

This thesis investigates the use of single liquid-crystal droplets as optical microresonators
and lasers. We have shown that liquid-crystal droplets can support a number of different …
