In this study, a wide-band photonic crystal Y-splitter for TE modes is proposed. A triangular lattice of air holes etched in a GaAs slab is used as the platform. In order to numerically analyze the structures, plane wave expansion (PWE) and finite difference time domain (FDTD) methods are used. In comparison with the structures reported in the literature, the proposed topology has a less complexity while it provides more than 100nm bandwidth. The simplicity of the design, its high transmission ratio and its wide bandwidth makes it a suitable choice for the implementation of photonic crystal integrated circuits.

“…Beam splitters are one of the central building blocks among the integrated components in PICs. These have been made by slab PhC [3][4][5][6][7][8][9][10][11], including Y-junctions [9][10][11], T-junctions [5,6] and directional couplers [3,4]. Until now, most of the work has focused on the performance of single-mode PhCW, but introducing multi-mode interference regions in the PhCWs provides new extraordinary characteristics [12] and some 1x2 components that use multimode interference have been proposed [7,8].…”

Based on inspiration from multi-mode interference self-imaging and theoretical FDTD simulations, a 1x3 beam splitter was designed, fabricated and characterized. Measurements show that for TE-polarized incident light the power is distributed equally between the output ports within 1dB in the range from 1541nm to 1552nm, and the total transmission of the 1x3 splitter is equal to the corresponding length of a single-linedefect PhCW within the measurement uncertainty.
