Abstract
A technique for an all-optical storage of multi-bit binary words in the form of 'bright' guiding-center solitons is presented. This technique has its origin in previously elaborated method of additive active mode-locking. An improved description of additive active mode-locking regime in semiconductor laser with an external fiber cavity is developed and analytical solution to this problem in steady-state regime is found with due regard for the phase effects. Picosecond optical guiding-center solitons of the first order, inherent in the systems of Ginzburg-Landau type, are considered as the bit carriers. Here, the model, described by the complex cubic Ginzburg-Landau equation, is analyzed and a new approximate analytical description in terms of Gaussian functions for the evolution of the main parameters of 'bright' guiding-center solitons in optical fiber is presented. The technique under consideration is based on matching the parameters of optical pulses in semiconductor laser structure by the parameters of guiding-center solitons in single-mode fiber. Some performance data of the memory device, maintaining the non-stop circulation guiding-center soliton digital trains and providing both all-optical and electronic access to the memory, are estimated.
