A 325 GHz analog photonic link (APL) is demonstrated by employing a recently reported 500 GHz bandwidth Mach-Zehnder modulator and a uni-travelling carrier photodetector. The link features a flat response over more than 100 GHz, only limited by the frequency range of the electrical spectrum analyzer extension module used. To our knowledge, this is the highest-frequency and most broadband APL characterized to date. The proposed approach may be useful to implement radio-over-fiber links at THz frequencies in future wireless applications and to enable microwave photonics functions to reach the sub-millimeter and THz range.
