title: Distribution of photonically generated 5 Gbits/s impulse radio ultrawideband signals over fiber.
abstract: We propose an approach to generate ultrawideband (UWB) pulses with tunable high-speed modulation based on pulse compression. Flexible generation of up to a record 5 Gbits/s on-off keying impulse radio UWB signals are successfully demonstrated as well. We also investigate 5 Gbits/s on-off keying bit-error-rate (BER) performance after 40 km single mode fiber transmission by employing a digital signal processing receiver, and the BER below forward error correction limit is achieved.
