The transmission spectral characteristics of the cascaded tilted long period fiber grating (CTLPFG) are studied theoretically and experimentally. Based on the coupled-mode theory and transfer matrix method, the effects of cascading lengths, cascading location, the number of cascades and tilt angle on CTLPFG transmission spectrum are simulated. The transmission spectrum of the CTLPFG is consistent with the transmission spectrum of the cascaded long period fiber grating (CLPFG) in cascading length and cascading location. The loss peaks of the second and 3rd- order cladding modes increase as the tilt angle is enhanced, and the second- order cladding mode is stronger than the 3rd-order mode. The second-order transmission spectra are sensitive to changes in the inclination for the angle above 60°. The width of the pass-bands increases along with the increase of the cascaded segments number, and they are in linear relationship. The results show that CTLPFG has a good value in a bimodal filter. CTLPFGs are made in experiments through point by point. Experimental results and theoretical simulations are comparatively analyzed, which demonstrates that they are in favorable consistency.
