A Passband and Stopband Switchable Microwave Photonic Filter Based on a Silicon Nitride Microdisk

摘要

Narrow bandwidths about 300 MHz and 418 MHz were obtained for the stopband and passband microwave photonic filters, respectively. High RF rejection ratio was larger than 51 dB and the frequency tuning range was 2-25GHz. © 2020 The Author(s)
