Abstract A new seven-channel transmission grating with plus-shaped array under normal incidence is proposed and discussed in this paper. Through the simulated annealing (SA) algorithm rigorous coupled-wave analysis (RCWA), novel microstructure can split incident energy into 0-th/±1-st/±2-nd/±3-rd orders evenly. The influence of angle, period, wavelength, other parameters on diffraction efficiency are also analyzed For transverse magnetic (TM) polarization, range period 3062–3246 nm bandwidth angle wavelength 1.96° 32.3 nm, respectively. It be concluded that TM-polarized light designed has a good performance fabrication tolerance. In addition, electric (TE) polarization satisfactory uniformity 2.40%. Therefore, certain significance for research multi-port beam splitter, especially polarization-independent splitter.

Abstract In order to meet the requirements of a multi-beam splitter in optical communication systems, an efficient infrared nine-channel reflective polarization-dependent beam based on addition-shaped ridge structure is proposed. All structural parameters this are derived from rigorous coupled-wave analysis. Upon vertical entry plane wave with wavelength 800 nm into grating, for transverse magnetic polarization, diffraction efficiencies 10.66%, 10.69%, 10.65%, and 10.67% at 0th, ±1st, ±2nd, ±3rd ±4th orders, respectively. For electric orders 10.79%, 10.86%, 10.88%, 10.84%, addition, tolerance analysis paper reveals practicality efficiency splitter. Therefore, has good performance uniformity broad application prospects applications.
