摘要：
The technique of eliminating the higher-order modes in a few-mode optical fiber is proposed. The fiber is designed with a group of defect modes in the cladding. The higher-order modes in the fiber can be eliminated by bending the fiber to induce strong coupling between the defect modes and the higher-order modes. Numerical simulation shows the bending losses of the LP01 mode are lower than 1.5x10(-4) dB/turn for the wavelength shorter than 1.625 mu m. The proposed fiber can be bent multiple turns at small bending radius which are preferable for FTTH related applications.
