Abstract Two-dimensional layered monoelemental materials (Xenes) with excellent optoelectronic properties have various property-related applications, such as energy, biomedicine, and devices. Xenes also show performance in acting saturable absorbers (SAs) for obtaining ultrafast laser operations. Few-layer tellurene a typical Xenens exhibits distinct promising practical application potential, its nonlinear optical absorption characteristics related modulation applications been investigated...
Abstract Air-stable broadband saturable absorbers (SAs) exhibit a promising application potential, and their preparations are also full of challenges. Palladium selenide (PdSe 2 ), as novel two-dimensional (2D) layered material, exhibits competitive optical properties including wide tunable bandgap, unique pentagonal atomic structure, excellent air stability, so on, which significant in designing air-stable SAs. In our work, theoretical calculation the electronic band structures bandgap...
In this manuscript, the nonlinear absorption properties of Cr2Ge2Te6 and its application in ultra-fast optical modulation are investigated. Typical parameters, namely, coefficient (β), saturation intensity, depth measured to be ~1.66 × 10-9 m/W, 15.3 MW/cm2, 5.8%, respectively. To investigate feasibility using as an modulator, a ring-cavity passively mode-locked Er-doped fiber laser has been constructed. The output power/pulse, duration/pulse, repetition rate/signal-to-noise ratios for...

In this paper, a polarization-maintaining quad-wavelength (QW) single-frequency fiber laser (SFFL) at the C-band with novel and compact structure is demonstrated. Applying rate equations multiple coupled nonlinear Schrödinger equations, theoretical model of QW lasers established, then optical spectra, temporal evolution, stability are analyzed numerically. Based on analysis, QW-SFFL having an ultrashort linear distributed Bragg reflector cavity proposed. Utilizing wideband grating...
