The technological revolution of two-dimensional (2D) materials provides vitality for ultrafast optics. Compared with other 2D materials, indium sulfide (In2S3) has become an attractive candidate material in the field nonlinear optics because its high carrier mobility, photoelectric sensitivity, medium band gap, and absorption coefficient. However, optical effects have rarely been studied. In this work, we synthesized β-In2S3 nanoplates using hydrothermal method. saturable absorber based on...
This Letter shows the Vernier effect based on two segments of PANDA polarization maintaining fiber (PMF), whose lengths are 28 and 23 cm, respectively. The PMFs spliced together, angle between fast axes is set to 45°. cascaded PMF inserted in a Sagnac loop form an interferometer that can generate effect. spectrum consists finesse fringe envelope realizes simultaneous measurement strain temperature. provide temperature sensitivities 58.0 pm/με 1.05 nm/°C. provides 5.9 1.36
This paper presents an experimental study to investigate the seismic performance of concrete beam-column joints with Design for Deconstruction (DfD) connections, which are characterized by two reusable beams and one precast column. The mortise-tenon connection from timber structures was adopted in design a moment-resisting purpose. Seven full-scale were tested according two-series cyclic loading test program evaluate frame before deconstruction after reconstruction. It found that cracking...
A switchable and tunable dual-wavelength single-longitudinal-mode (SLM) fiber laser in a 2- $\mu \text{m}$ region based on saturable absorber self-injection locking is proposed experimentally demonstrated. The topology the parallel connection of Bragg gratings (FBGs) using coupler to realize switchability tunability by adjusting cavity losses center wavelengths FBGs, respectively. ensure stable operation at SLM.
