Description
Summary:Based on numerical solution to the nonlinear Maxwell—Bloch equations, the joint implementation of active (parametric) and passive (coherent) mode locking for a class-C heterolaser with a low-Q combined Fabry—Perot cavity in the presence of the effective distributed feedback of counterpropagating waves is demonstrated. It is shown that the multiplicity of the spectral width of the photonic band gap of the cavity to the intermode spacing far from this zone contributes to the effective phasing of quasi-monochromatic quasi-equidistant modes, thus maintaining their parametric coherent self-mode locking. A number of examples are used to demonstrate the typical properties of a quasi-periodic sequence of soliton-like pulses generated in the found mode, which does not require external modulation of the pump or laser parameters, or the placement of a fast-saturating absorber in it.
