500 GHz Technology from IEF: Featured Article in APL Photonics
The article from our group (Maurizio Burla et. al.) 500 GHz plasmonic Mach-Zehnder modulator enabling sub-THz microwave photonics - featuring the fastest Mach-Zehnder modulator to date - has been published online today, 30 May 2019, in APL Photonics (Vol.4, Issue 5). It has been selected as one of the journal’s best and highlighted as "Featured Article" on the main APL Photonics page.
We have experimentally demonstrated Mach-Zehnder modulators simultaneously meeting all requirements for analog applications, i.e., high linearity, high power handling, and speeds reaching 500 GHz. To our knowledge, we reported the fastest Mach-Zehnder modulator to date. We also demonstrate a radio-over-fiber link up to 325 GHz (>100 GHz bandwidth).
These results suggest that plasmonics has the potential for becoming a new tool to the field of microwave photonics, enabling applications to reach the sub-terahertz range, while preserving the high-performance required in large-scale analog applications such as 5G wireless, antenna remoting, IoT, sensing, and more.
