“…Multiwavelength fiber lasers (MFL) show promising qualities that can benefit many areas of expertise including optical communication, optical sensing network, gas spectroscopy, and also optical component testing [6,7]. These qualities encompass, but not limited to low production cost, low noise, flexible design, and multi-wavelength source [7,8]. Multiwavelength fiber laser can also function as a selectable wavelength laser source in a wavelength division multiplexing (WDM) system [9].…”

We demonstrated the generation of a multiwavelength laser comb through two different ring cavity designs. The first design, a ring laser with Sagnac filter is being modified to produce a second design known as composite ring cavity. The ASE spectrum obtained from the composite ring cavity is sliced into more than 30 laser lines. From this comb, 22 laser lines are flattened under the 3 dB peak power fluctuation and 25 lines are flattened under the 10 dB peak power fluctuation. The 24 laser lines have a bandwidth value of 10.48 nm and for each of them, the average OSNR value is found to be at 24 dB. The OSNR value distribution among the laser lines is nearly uniform. However, the fineness obtained in this scheme is very low as 2.8.

“…-1000 -500 0 500 1000 0.00 The switching mechanism can be qualitatively explained by the balance between the fiber gain and cavity loss. [17,18] When the cavity loss is low, the fiber gain is clamped at the low gain peak around 1560 nm. On the other hand, if the cavity loss is high, then the fiber gain must be clamped at the high gain peak around 1530 nm to compensate for the loss.…”

A simple scheme of switchable dual-wavelength passively mode-locked fiber laser is demonstrated. The laser can be flexibly switched among different mode-locked states simply by tuning the cavity loss while keeping all the other cavity parameters fixed. As the cavity loss increases, the mode-locked fiber laser operates at the long-wavelength, dual-wavelength, and short-wavelength states, successively. In addition, these states can be conveniently switched without losing the mode-locked operation and the switching process is reversible as the cavity loss decreases. The mechanism is qualitatively explained by the balance between the fiber gain and the cavity loss.
