摘要：
Chirped and apodized grating couplers were designed, fabricated and characterized in lithium niobate thin film for fiber-to-chip coupling. The maximum coupling efficiency of -1.8dB and -6.9dB for TE mode at a wavelength of 1550 nm was simulated and measured, respectively. The discrepancies were mainly attributed to the different fabrication errors of local periods and groove widths, which hampered the mode matching condition heavily. In addition, when a metal bottom reflector was added, the simulated and measured coupling efficiency were improved to -0.8 dB and -5.5 dB, respectively.
