| Abstract: | The mechanical-induced long-period fiber grating(LPFG) is obtained by pressing the fiber in single side,whose cladding is etched by HF solution,and the pitch of the grooved plate is 600 μm.The influence of the cladding diameter on the coupling characteristics between the core fundamental mode and the cladding LP12 and LP13modes is analyzed by measuring the transmission spectra of LPFGs with different cladding diameters under different pressurs.Experimental results show that the red-shift of the resonant wavelength and the coupling coefficient increase as the cladding diameter decreases.The over-coupling of the LP13 mode is faster than the LP12 mode as the cladding diameter is more than 107 μm.And the opposite phenomenon happens as the cladding diameter is less than 107 μm.The results imply that etching the cladding is an effective method to improve the coupling efficiency between the core mode and the cladding mode. |
