摘要

在薄膜铌酸锂(TFLN)平台上，采用开槽贴片天线和嵌入式光波导，设计了一种集成的微波-光转换器。该转换器设计工作在28ghz的中心频率，3db带宽为4ghz。实验结果表明，在29.5 GHz频率下，在82 V/m的入射电场下，3db带宽为3.5 GHz，载波边带比(CSR)为40 dB。

Integrated Microwave-to-Optical Converter Using Patch Antennas on Thin-Film Lithium Niobate

An integrated microwave-to-optical converter is demonstrated using a slotted patch antenna and an embedded optical waveguide fabricated on the thin-film lithium niobate (TFLN) platform. The converter is designed to operate at the center frequency of 28 GHz with a 3-dB bandwidth of 4 GHz. Experimental results exhibit a 3-dB bandwidth of 3.5 GHz and a carrier-to-sideband ratio (CSR) of 40 dB under an incident electric field of 82 V/m at 29.5 GHz frequency.
