Solar photovoltaics based on synthetic halide perovskites have revolutionized solar energetics in the last decade. Since 2009 overall efficiency of sunlight-to-electricity conversion perovskite cells increases from 3.8% up to 25.5% (for thin-film single-junction cells) and more than 30% affordable tandem with top photovoltaic layer perovskite). On other hand, nanophotonics has made a huge progr...

Miniature slow light devices based on the recently developed Surface Nanoscale Axial Photonics (SNAP) technological platform is reviewed. The theory and experimental demonstration of the SNAP bottle resonator dispersionless delay line and dispersion compensator are presented. Keywords— Nanophotonics, microresonators, microfibres

The success of information technology has clearly demonstrated that miniaturization often leads to unprecedented performance, and unanticipated applications. This hypothesis of "smaller-is-better" has motivated optical engineers to build various nanophotonic devices, although an understanding leading to fundamental scaling behavior for this new class of devices is missing. Here we analyze scali...
