“…For instance, Wang et al [16] has demonstrated a controllable dissipative soliton and Q‐switched pulse emission in a normal dispersion fibre laser. In other works, Gao et al [17] reported on switchable function between passive single‐pulse and multiple‐pulse mode‐locking, coherent pulse pattern and passive Q‐switching, whereas Lin et al [18] demonstrated switchable operation modes between continuous wave, Q‐switched mode‐locking, pulse splitting and harmonic mode‐locking.…”

The authors demonstrate a controllable generation of a stretched pulse and dissipative soliton in a normal dispersion erbium-doped fibre laser (EDFL) based on non-linear polarisation rotation technique. It is found that the mode-locking could selfstart in the EDFL even without inserting a polariser in the cavity because of the large residual polarisation-dependent loss of a cavity component. By slightly adjusting a polarisation controller, a stretched pulse can be switchable to the dissipative soliton, while maintaining the repetition rate of 2.5 MHz. The stretched pulse has a pulse width of 0.35 ps with energy of 127.6 pJ, whereas the dissipative soliton has a pulse width of 0.60 ps with energy of 208.4 pJ.

“…Tian et al [16] demonstrated the switchable function of mode locking and continuous wave (CW) single-wavelength and multi-wavelength lasing using nonlinear optical loop mirror configuration. Gao et al [17] reported on switchable functions between passive single-pulse and multiplepulse mode locking, coherent pulse pattern, and passive Q switching. In this letter, a switchable Q-switched and mode-locked EDFL operating in the L-band region is demonstrated based on a switchable NPR effect using a Mach-Zehnder interferometer (MZI) as a comb filter.…”

We demonstrate a switchable Q-switched and mode-locked erbium-doped fiber laser (EDFL) operating in the L-band region using the nonlinear polarization rotation effect. The switching operation is achieved by controlling intensity-dependent loss using a polarization controller. In Q-switching mode, the EDFL produces a pulse train with a repetition rate of 21.1 kHz, pulse width of 7.7 µs, and pulse energy of 13.6 nJ. The EDFL also generates a multi-wavelength comb with a very narrow and constant wavelength spacing of 0.045 nm and optical signal-to-noise ratio of at least 10 dB. During mode locking, the EDFL produces stretched pulses with 3-dB bandwidth of 26.2 nm, pulse width of 350 fs, repetition rate of 2.38 MHz, and pulse energy of 48.56 pJ. OCIS codes: 320.0320, 140.0140.

Widely tunable dispersive waves (DW) and Raman solitons are generated in a tellurite microstructured optical fiber (TMOF) by pumping in the anomalous dispersion regime, close to the zero dispersion wavelength (ZDW). The DW can be generated from 1518.3 nm to 1315.5 nm, and the soliton can be shifted from the pump wavelength of 1570 nm to 1828.7 nm, by tuning the average pump power from 3 dBm to 17.5 dBm. After the average pump power is increased to 18.8 dBm, two DW peaks (centered at 1323 nm and 1260 nm) and three soliton peaks (centered at 1762 nm, 1825 nm, and 1896 nm) can be observed simultaneously. When the average pump power is greater than 23.4 dBm, a flat and broadband supercontinuum (SC) can be formed by the combined nonlinear effects of soliton self-frequency shift (SSFS), DW generation, and cross phase modulation (XPM).
