100-GHz Radio and Power Over Fiber Transmission Through Multicore Fiber Using Optical-to-Radio Converter

We designed and fabricated a 100-GHz range integrated photoreceiver with zero-bias operational uni-traveling-carrier photodiode and pseudomorphic high electron mobility transistor amplifier, which performed the roles of photonic power generation and 100-GHz RF signal generation. Using the integrated photoreceiver, high data rate radio- and power-over-fiber transmission through multicore fiber communication was demonstrated. Subsequently, a bit error rate of $1\times 10^{- 3}$ could be achieved with 12 Gb/s, orthogonal frequency division multiplexing, 16 quadrature amplitude modulation, and an intermediate frequency of 92 GHz. The crosstalk issue in radio- and power-over-fiber transmission through multicore fiber was discussed.
