Over the past two decades, fiber laser technologies have matured to such an extent that they
have captured a large portion of the commercial laser marketplace. Yet, there still is a …

Oil and gas (O&G) explorations moving into deeper zones for enhanced oil and gas
recovery are causing serious safety concerns across the world. The sensing of critical …

Robust low-loss optical fiber joints are a prerequisite in all-fiber devices. Joining structurally
dissimilar fibers, such as microstructured optical fibers, is a timely challenge, as they are …

Yb3+/Al3+/P5+-co-doped silica glasses with different P/Al ratios were prepared using the sol–

Ultrashort pulses at 920 nm are a highly desired light source in two-photon microscopy for
the efficient excitation of green fluorescence protein. Although Nd3+-doped fibers have been …

A novel scheme for fabricating Yb-doped silica micro structured optical fibers and their
application in high-temperature optical fiber sensing are reported. The Yb-doped silica micro …

A series of Yb-doped silica glasses containing equimolar amounts of P 2 O 5 and Al 2 O 3
were prepared using a sol–gel method combined with high-temperature sintering. Raman …

In this work, the effect of Nb 2 O 5 oxide on the∼ 2.0 μm band luminescence of Ho 3+/Tm
3+/Ce 3+ tri-doped tellurite glass with composition of TeO 2–ZnO–La 2 O 3 was studied. The …

In this study, Er^ 3+/Yb^ 3+/Al^ 3+/P^ 5+-doped silica (simplified as EYAPS) glasses with
different P/Al ratios ranging from zero to infinity were fabricated via the sol-gel method …

The molecules of nematic liquid crystal rotate as the ambient voltage increases. A photonic
crystal fiber with many holes distributed on its cross section provides a platform to integrate …
