英文摘要	A novel hollow-core (HW) Y-branch waveguide splitter based on high-contrast grating (HCG) is presented. We calculated and designed the HCG-HW splitter using Rigorous Coupled Wave Analysis (RCWA). Finite-different timedomain (FDTD) simulation shows that the splitter has a broad bandwidth and the branching loss is as low as 0.23 dB. Fabrication is accomplished with standard Silicon-On-Insulator ( SOI) process. The experimental measurement results indicate its good performance on beam splitting near the central wavelength lambda = 1550 nm with a total insertion loss of 7.0 dB.; Engineering, Electrical & Electronic; Optics; Physics, Applied; EI; CPCI-S(ISTP); 0
