A 24-GHz Ultra-Wideband Over Fiber System Using Photonic Generation and Frequency Up-Conversion

Abstract—We propose and experimentally demonstrate the generation of baseband ultra-wideband (UWB) monocycle and doublet pulses using one dual-parallel Mach–Zehnder modulator. We further present a proof-of-concept demonstration of a 24-GHz UWB over fiber system based on frequency up-conversion. The performance of the up-converted UWB pulses after fiber trans-mission is studied. Index Terms—Dual-parallel Mach–Zehnder modulator (DPMZM), ultra-wideband (UWB) over fiber, up-conversion
