Study on a tunable radio frequency filter based on integrated optical waveguide: 点击次数：; 发布时间： 2019-03-12; 发布时间：2019-03-12; 论文类型：期刊论文; 发表时间：2013-10-01; 发表刊物：Guangxue Xuebao/Acta Optica Sinica; 收录刊物：Scopus、ISTIC、PKU、EI; 卷号：33; 期号：10; ISSN号：02532239; 摘要：A new tunable microwave photonic filter combining optical waveguide micro-ring resonator and Mach-Zehnder interferometer (MZI) is proposed to realize single sideband filtering. The influences of the filter structural parameters, such as coupling coefficient r, round-trip loss 1 and additional phase shift 1, etc., on the filtering response are investigated. The result shows that there is a tradeoff between the rectangle shape and extinction ratio. According to the polymer polysilsesquioxane-liquid (PSQ-L) waveguide, a microwave photonic filter with rectangle shape factor of 0.8 and extinction ratio of 32 dB is designed, and the tunable radio frequency single sideband filtering from 8 GHz to 69 GHz can be achieved with the thermal-optic phase shifters.
