We study the dynamics of lasers with nonlinear loss theoretically. Our simulations show that depending on the laser parameters, the laser output can exhibit stable, periodic bifurcation, or chaotic behavior.
We theoretically studied the operation of a laser with homogeneous gain and nonlinear loss. Multi-wavelength operation is possible because the nonlinear loss provides an adaptive balance to the different gain values at different wavelengths.
A novel and simple multiwavelength erbium-doped fiber laser is proposed and demonstrated. The combination of a polarization scrambler and a polarizer is employed to induce polarization-dependent-loss modulation. The loss modulation induced multiwavelength lasing by alleviating the mode competition caused by homogeneous gain broadening of the erbium-doped fiber. As a result, 11-wavelength lasing operation...
A switchable multiwavelength erbium-doped fiber laser with a multimode FBG and highly nonlinear PCF is demonstrated. Stable five-wavelength operation with 0.8 nm spacing was achieved. Switching between stable one- to four-wavelength operations is also demonstrated.
