A Multidimensional Multiplexing Soliton Fiber Laser

Abstract

The invention discloses a multi-dimensional multiplexing soliton optical fiber laser device which comprises a laser pump source and an annular laser resonant cavity consisting of a gain medium, a dispersive medium, a wavelength division multiplexer, an optical coupler, an optical circulator, a polarization controller and a polarizer. The laser pump source and the gain medium work together so as toprovide a gain amplification mechanism for laser device operation. The dispersive medium can be used for chromatic dispersion compensation of pulse laser so as to achieve chromatic dispersion management of an internal optical path of the laser device, and the optical circulator is a non-reciprocal optical transmission device for coupling the chromatic dispersion medium to construct a bidirectional transmission optical path structure. Via use of the polarization controller, a local polarization state of the internal optical path of the laser device can be changed, and mode-locking operation ofthe pulse laser and adjustment and switching of a mode-locking state can be realized. The multi-dimensional multiplexing soliton optical fiber laser device of the invention can be used for bidirectional transmission, and mode-locking laser pulses can be respectively obtained, generation of polymorphic soliton pulses can be supported, and a wideband wavelengths tuning function and a multiple wavelength switching function can be fulfilled via output laser pulses.
