We experimentally demonstrate a power-efficient ultrawideband (UWB) generation scheme using an electro-optic phase modulator. The generated UWB pulses are fully Federal Communication Commission compliant with high power efficiency of 52.6%. Furthermore, 2-Gbit/s on-off keying modulated modified UWB triplet signals are transmitted over 20 km optical fiber link without any obvious spectra or pulse shape distortions, and error-free transmission is achieved with power penalties less than 1.5 dB.
