Targeting the huge unused bandwidth (BW) of modern telecommunication networks, Bi/Er
co-doped silica optical fibers (BEDFs) have been proposed and developed for ultra …

Research on glass nanocomposites (GNCs) has been very active in the past decades.
GNCs have attracted—and still do—great interest in the fields of optoelectronics, photonics …

Hybrid or composite nanomaterials have emerged that demonstrates superior optoelectronic
performance over pure nanomaterials that lacks broadband usage, or responsivity, or both …

This paper presents a novel approach to attain a single-polarization-single-mode (SPSM)
photonic crystal fiber (PCF) in the terahertz (THz) regime. An initial circular hole PCF design …

Layered 2D semiconductors are characterized by unique photoelectric properties and,
therefore, constitute a new class of basic building block for next‐generation optoelectronics …

The development of high‐quality and strongly Au conjugated upconversion nanoparticles
(UCNPs) is time‐consuming and requires specific chemicals. Therefore, a one‐pot …

Two kinds of Yb-doped fibers were fabricated, namely, Yb: YAG crystal-derived silica fibers
(YCDSFs) with a gain coefficient of 6.0 dB/cm, and Bi/Er/Yb co-doped silica fibers having a …

A novel terahertz (THz) photonic crystal fiber (PCF) that yields single-polarization single-
mode (SPSM) propagation over an ultra-wide bandwidth is designed and analyzed. The …

The effect of copper nanoparticles (CuNP) on the enhancement of the infrared and
upconversion emissions intensities in the Er 3+/Yb 3+/Ce 3+ co-doped transparent tellurite …

In this study, the influence of ytterbium ions (Yb^ 3+) on the fluorescence lifetime of erbium
(Er)-doped silica optical fiber (EDF) is investigated. An Er/Yb co-doped fiber is fabricated by …
