Abstract
We present a 100-GHz narrowband optical-to-radio converter driven by power over fiber (PoF), and discuss about the fundamental radio over fiber communication performance and the settling time performance in radio launching driven by PoF. The 100-GHz optical-to-radio converter consists of a zero-bias operational 100-GHz UTC-PD and a 100-GHz GaAs-based enhancement type pHEMT amplifier. The generated electrical power through a power converter in PoF was applied to the drain bias, and the generated small power through the UTC-PD was applied to the gate bias. While turning ON/OFF optical power rapidly in PoF, the settling performance in 100-GHz radio launching was investigated.
