2014 INTERNATIONAL TOPICAL MEETING ON MICROWAVE PHOTONICS (MWP) AND THE 2014 9TH ASIA-PACIFIC MICROWAVE PHOTONICS CONFERENCE (APMP) 157 - 159 2014年
記述言語：英語 掲載種別：研究論文（国際会議プロシーディングス） 出版者・発行元：IEEE
We investigate a technique to suppress undesired third-order harmonics of two-tone lightwave signals using cascaded Mach-Zehnder modulators. Third-order harmonics, which determines the signal-to-noise ratio and side-mode suppression ratio, are dominant spurious components in two-tone lightwave signals. We were able to improve the linearity of modulator and demonstrated 14 dB suppression of third-order harmonics at 10 GHz with the technique.

記述言語：英語 掲載種別：研究論文（国際会議プロシーディングス） 出版者・発行元：IEEE
We have successfully realized the non-bias operation of an ultra-wide bandwidth uni-traveling-carrier photodetector (UTC-PD) using a low carrier concentration of 3 x 1014 cm(-3) in the carrier collection layer for future high-density photonic integration. A 3-dB bandwidth above 110 GHz was confirmed without a bias circuit. In this paper, we discuss the proposed design and the experimental results obtained for the frequency response and maximum RF output power.

記述言語：英語 掲載種別：研究論文（国際会議プロシーディングス） 出版者・発行元：IEEE
The technology of encapsulating a microwave signal into a terahertz carrier and an optical signal is proposed and demonstrated experimentally. Broad bandwidth terahertz radio can encapsulate existing microwave services, including advanced mobile communication signals, by using photonics technology. The concept of radio-on-terahertz-over-fiber helps to realize the future design of mobile fronthaul links. These links will have seamless connectivity between radio and optical networks because of the low latency of the links, which results from the use of analog signal transmission technology.
