In this paper, we demonstrated a passively mode-locked erbium-doped fiber laser by incorporating a microfiber-based tungsten diselenide (WSe2) saturable absorber (SA). We obtained stable mode-locking with pulse duration of 1.2 ps, repetition rate of 2.6 MHz and signal-to-noise ratio (SNR) of 66 dB at maximum pump power of 400 mW. The experimental results show that CVD-grown WSe2 film can serve as...
In this paper, a novel microfiber refractive index sensor prepared with tapering-twisting-tapering technique has been proposed and demonstrated for the first time. Experimental results show that the interference intensity of the novel microfiber increases with the increment of pre-tapered length and the intervening twist number. Furthermore, the refractive index sensitivity of this microfiber sensor...
In this work, a hybrid plasmonic microfiber knot resonator (HPMKR) is demonstrated as well as its multi-sense applications. A microfiber knot resonator (MKR) is attached to gold film and generates the hybrid plasmonic mode. The HPMKR has an extinction ratio of more than 10 dB in C-band, with the Q-factor of more than 47,000. For a chosen polarization, the resonator has an extinction ratio of nearly...
We experimentally demonstrate a new method for modulating the light polarization state of the fiber. Both of the light polarization degree and polarization direction can be modulated. In the experiment, microfiber is immersed into the magnetic fluid (MF). When there is external magnetic field, magnetic nanoparticles of the MF generate magneto-optical dichroism and a non-circular symmetric distribution...
We report on the generation of versatile pulse patterns in an erbium-doped fiber laser incorporating a 2D nano-materials, topological insulator (TI): Bi2Te3. By depositing of the TI on a microfier, an effctive saturable absorber (SA) would be created, which has combined the advantages from the strong nonlinear optical response in TI material together with the suffiently-long-range interaction length...
We demonstrated the passively Q-switched Erbium-doped fiber laser by the microfiber-based PbS quantum dot (QDs) as saturable absorber (SA). Compared with other SA, the microfiber-based PbS QDs had higher thermal damage threshold and tunable spectroscopic properties. We fabricated the microfiber with the diameter of 5.86 μm and the interaction length of 2 mm and the PbS QDs with the peak of absorption...
