Paper Abstract

A 1×5 transmission grating splitter with triangular structure under normal incidence at the wavelength of 1550 nm is presented in this paper. In order to further increase the efficiency, the material of the designed grating is MgF2. The whole transmitted diffraction efficiency of the gratings is over 99% with uniformity better than 0.3%. The designed parameters of this triangular grating are employed by the rigorous coupled-wave analysis and the simulated annealing algorithm. This grating has a large tolerance for fabrication with better performance, which should be highly interesting for practical applications.
