TiN nanoparticles deposited onto a D-shaped fiber as an optical modulator for ultrafast photonics and temperature sensing

Abstract

Titanium nitride (TiN) with outstanding physical and chemical properties, has earned as much attention. However, few studies has been conducted on the ability of TiN in ultrafast photonics field. In...

Carbon Nano-onions as Saturable Absorbers for Pulsed Fiber Lasers

“…A nonlinear model described in the SI was adopted to match the measured data in Figure 2d. 30 The modulation depth α s and nonsaturable loss α ns were 7.6 and 37.5% at 1.56 μm. Using the same method, the saturable absorption properties were also investigated at 1 (11.5 and 27.3%) and 2 μm (7.2 and 42.6%) as displayed in Figure 2c,e.…”

“…The balanced twin-wall test system was built to present the nonlinear properties of the fabricated CNO film (Figure S2). A nonlinear model described in the SI was adopted to match the measured data in Figure d . The modulation depth α s and nonsaturable loss α ns were 7.6 and 37.5% at 1.56 μm.…”

Preparation and pulsed fiber laser applications of emerging nanostructured materials

“…363 4.1.2.5 Metal nitrides and metal phosphides. There are reports about the plasmonic metal nitrides and phosphides such as TiN, [364][365][366] InN, 367 and Cu 3Àx P nanostructured materials 368 as the SAs for applications in passively modelocked fiber lasers. For instance, Xian et al reported the passively mode-locked fiber laser centered at 1562 nm with pulsed duration down to 763 fs in EDFL by using the TiN nanoparticles as the SA in 2019 (Fig.…”

“…364 The TiN nanoparticles were also applied as the SA for generation of passively mode-locked TDFL centered at around 2 mm. 366 Nanocomposite such as the Au nanocluster-modified TiN nanomaterial was also applied as the SA for generation of passively mode-locked laser pulses in EDFL. 369 In summary, the nanostructured materials have been widely used as SAs for generation of laser pulses in the passively modelocked fiber lasers due to their advantages such as broadband saturable absorption performance, ultrafast response, as well as facile preparation and integration.…”
