Current photonic crystal devices have seen limited research on the integration of beaming of light emitting and filtering functionalities,often exhibiting suboptimal performance in this combined role.To achieve a reliable and efficient integration of filtering and beaming of light emitting,this paper proposes a V-shaped,two-dimensional square-lattice photonic crystal waveguide structure designed for beaming of light emitting alongside filtering.The structure features a main waveguide trunk that splits into two branches.The interference between the trunk and the branches enhances the bundle performance,leading to a significant improvement in the effective propagation distance.Four filtering micro-cavities are incorporated prior to the exit ports,designed to reject four specific central wavelengths:1.452 μm,1.493 μm,1.562 μm,and 1.664 μm,with respective filtering efficiencies of 99.8%,97.4%,97.5%,and 99.1%.Testing of the bundle structure demonstrates its exceptional ability to collimate light in the non-filtered (pass-band) wavelength regions.Specifically,at wavelengths of 1.310 μm and 1.340 μm,the effective propagation distances are measured to be 397.7 μm and 445.9 μm,respectively.
