The influence of the difference between the top width and the bottom width (simplified to d in the following text) of the trapezoid index modulation on the transmission characteristics is analyzed. Calculated results show that the resonance location displaces to the long wavelength when the d increases. Compared with the long-period fiber grating with rectangle index modulation, the advantage of this novel grating is that it needs a smaller refractive index change. When d is zero, this model can be used to simulate the LPG with a rectangular index modulation, and the theoretical results are in good agreement with the experimental ones.}, title={Transmission analysis of long-period fiber grating with trapezoid index modulation}, type={artykuł}, keywords={optyka, long-period fiber grating, trapezoid index modulation, transmission spectrum}, }
