Abstract

We present the simulation method to calculation of arbitrary fiber grating (apodized, chirp etc.) with high precision by combination of methods based on layered dielectric media (LDM) and transfer matrix. On the contrary to the other calculation techniques the LDM method is based on sequence of thin films of dielectric media assembled in the direction of wave propagation. The critical parameter of fiber gratings, the bandwidth can be narrowed by higher refractive index change, longer gratings or by multiplying fiber gratings. On the basis of our simulations and measurements of the commercially available fiber gratings we designed a special 100 mm long fiber Bragg grating with apodization. Finally, we simulated parameters of fiber gratings arrays-multiple fiber gratings. We expect the application of FBGs to improvement of the linewidth and mode-hop free tuning range of semiconductor lasers at the wavelength 760 nm to increase resolution of fiber laser interferometer based on these laser diodes.
