Abstract Spin–orbit coupling (SOC) in tightly focused optical fields offers a powerful mechanism for manipulating the complex motion of particles. However, to date, such has only been applied single-orbit particles, while multi-orbital dynamics have not yet experimentally demonstrated. Here, theoretical and experimental realization dual-orbit rotational nanoparticles circularly polarized Laguerre-Gaussian beam is reported. Analyses reveal that rotation originates from SOC vortex beam, with...

A fiber Bragg grating written in a photosensitive microfiber using KrF excimer laser via uniform phase mask is demonstrated. We have successfully fabricated two gratings microfibers having different diameters. In the reflection spectrum of (MFBG), we observed peaks,which agrees with our numerical simulation results. Compared fundamental mode reflection, higher-order more sensitive to refractive index (RI) variation surrounding fluid due its larger evanescent field. The measured maximum...
Using the measured capacitance-voltage curves of Ni Schottky contacts with different contact areas and current-voltage characteristics for circular rectangular AlGaN/AlN/GaN heterostructure field-effect transistors (HFETs) at low drain-source voltage, we found that polarization Coulomb field scattering has an important influence on two-dimensional electron gas (2DEG) mobility in both HFETs. Moreover, heterostructures is relatively weaker compared to AlGaN/GaN heterostructures, which...
