Generation of switchable multi-wavelength solitons in a fiber laser mode locked by MoS2-wrapped microfiber

In this paper, a switchable multi-wavelength fiber laser mode locked by molybdenum disulfide (MoS2) film wrapped microfiber is demonstrated. By tuning intra-cavity loss and linear birefringence, switchable single-, double-, and triple-wavelength conventional solitons (CSs) are formed. Additionally, quadruple-wavelength solitons with center wavelengths of 1528 nm, 1532 nm, 1552 nm, and 1562 nm are realized by precisely adjusting the polarization controller (PC) and pump power. Experimental results demonstrate that this compact and versatile multi-wavelength soliton laser has significant potential for various applications.
