Down Conversion Less Monitoring Method for Beyond 5G RF Signal in RoF

Abstract (in Japanese) (See Japanese page) 
(in English) Various research and development on Beyond 5G is being actively achieved and they aim to build a new communications infrastructure to combine wired, wireless, optical, and radio waves. There, the transmission of high-frequency signals by radio-fiber radio (Radio-over-fiber: RoF), which has high transmission efficiency, is also being vigorously studied. However, as both of the carrier and base-band frequencies increase furethermore, issues in down conversion have become more apparent and various studies for substitued approaches are currently underway. We also have proposed a method to realize direct monitoring of high-frequency signals without down conversion but with a designed optical probe for time-wavelength mapping. In this paper, we show the experiemntal results of simultaneous monitoring of a 20 GHz carrier signal and a 100 MHz baseband signal with our approach.
