Digitally tunable optical delay line based on thin-film lithium niobate featuring high switching speed and low optical loss
文献摘要：
A tunable optical delay line(ODL)featuring high switching speed and low optical loss is highly desirable in many fields.Here,based on the thin-film lithium niobate platform,we demonstrate a digitally tunable on-chip ODL that includes five Mach-Zehnder interferometer optical switches,four flip-chip photodetectors,and four delay-line waveguides.The proposed optical switches can achieve a switching speed of 13 ns and an extinction ratio of 34.9 dB.Using a modified Euler-bend-based spiral structure,the proposed delay-line waveguide can simultane-ously achieve a small footprint and low optical propagation loss.The proposed ODL can provide a maximum delay time of 150 ps with a resolution of 10 ps and feature a maximum insertion loss of 3.4 dB.
