Highly-nonlinear-fiber-based devices have become an attractive research topic in the field of ultra-high-speed photonic information processing due to the fiber's unique features, such as inherent THz bandwidth, fast nonlinear response with femto-second order of magnitude, and easy quick interconnection. This project will focus on what follows: (1) combine magneto-optics with nonlinear fiber optics, establish the propagation and control theory for optical guided waves in magneto-optical nonlinear fibers, and investigate the micro-mechanism of magneto-optic effects; (2) verify the magnetic control mechanism of fiber nonlinearity by experiments and enhance the controllability of intelligent fiber-optic information processing devices for the next generation of optical fiber communications; (3) improve the operating performance and increase useful functions of nonlinear fiber devices by optimizing the magneto-optic parametric process, including the implement of magnetically tunable gain, the improvement of four-wave-mixing-based pulse reshaping, magnetic control function of nonlinear Sagnac switching, and fiber-optic-parametric-oscillator (FOPO)-based stable clock extraction, etc.
