“…In their experiments, the two counter propagating pulse trains exhibited very similar performance in terms of pulse duration, spectrum, and repetition rate. By using two SESAMs, Ouyang et al reported a bidirectional passively mode-locked fiber laser at 1.56 μm [18]. In their work, much of the focus is on the different output properties of two counter-circulating pulse trains.…”

We present an all-fiber bidirectional passively mode-locked soliton laser with a graphene-based saturable absorber for the first time to the best of our knowledge. Our design includes a four-port circulator to introduce different sections of cavity for the two counter-propagating pulses, so they have distinct output characteristics. Simultaneous bidirectional operation is achieved by appropriately adjusting the net cavity birefringence and loss. In the clockwise direction, the laser emits ~750 fs pulses at 1561.6 nm, with a repetition rate of 7.68 MHz. In the counter clockwise direction, the central wavelength, pulse width, and repetition rate are 1561.0 nm, ~850 fs, and 6.90 MHz, respectively.

“…Due to the asymmetry of cavity elements, as shown in Fig. 1, pulses propagating in the CW and CCW directions pass through each element in reverse order and experience different cavity dispersion [45], which leads to the different pulse features. On the other hand, fiber birefringence plays an important role for these unique features.…”

The bidirectional stretched pulses in a nanotube-based erbium-doped fiber laser are observed experimentally for the first time to our best knowledge. The proposed fiber laser generates two stable pulse trains in opposite directions with different central wavelengths, pulse widths, and repetition rates. In addition, the bidirectional operations with the same central wavelengths are also demonstrated by changing the polarization controller and pump power. Experimental results suggest that the cavity asymmetries together with the fiber birefringence play key roles in the formation of these unique features.
