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.

Description

technical field [0001] The invention belongs to the fields of fiber lasers, ultrafast optics and nonlinear optics, in particular to the bidirectional output of traditional solitons and dissipative solitons, as well as multi-wavelength, broadband tunable pulsed lasers and other phenomena. It has research value and potential applications in fields such as optical logic systems, and more specifically, relates to a multi-dimensional multiplexing soliton fiber laser. Background technique [0002] Wavelength is an important basic physical quantity for light, and it is also an important application dimension in optoelectronic information technology and related fields. Opening up channels on different optical bands and loading information for transmission at the same time is the basic principle of realizing wavelength division multiplexing optical fiber communication and sensor networking, which can double the communication capacity. In the field of fiber lasers, passive mode locki...
