Abstract
The generation of ultra-wideband (UWB), high-frequency waveforms based on
nonlinear propagation of pulses in optical fibers is reported. Self-phase
modulation and subsequent optical filtering are used to implement
all-optical edge detectors, which generate two temporally-narrowed replicas
of each input pulse. The shapes of the narrowed pulses are subtracted from
that of the original one in a balanced differential detector, providing a
UWB waveform. The use of multiple replicas and nonlinear propagation allows
for the generation of higher-order pulse shapes, beyond those of a Gaussian
monocycle or doublet. The output pulse shape is reconfigurable through
adjusting the input power and detuning the optical filters. The central
radio-frequency of the generated waveforms is as high as 34 GHz, with a
fractional bandwidth of 70%.
