A linear phase-modulated photonic link based on optical carrier band (OCB) processing is proposed. By introducing a proper phase shift to the OCB, the third-order intermodulation distortion (IMD3) component of the signal transmitted over a length of fiber is effectively power faded, while the fundamental component is almost maintained. The IMD3 is effectively suppressed to realize a linear phase-modulated...
A simple scheme to simultaneously generate a UWB signal and a wired signal in the optical domain using a dual-drive modulator is proposed and demonstrated. A 1.25-Gb/s optical UWB signal and 1.25-Gb/s wired signal are generated, which are then transmitted over a 36-km single-mode fiber (SMF). Eye diagrams, electrical spectra and BER measurements show that the interference between the two signals is...
The distribution of ultra-wideband (UWB) signals over optical fiber, or UWB over fiber (UWBoF), is proposed to extend the area of coverage and to offer the availability of undisrupted service across different networks. Various techniques have been reported recently for optical UWB pulse generation, but the study on the implementation of different modulation schemes based on these UWB pulses has just...
Highly chirped optical UWB pulses with wide optical spectral widths tend to be distorted by fiber dispersion, which is undesirable for UWB over fiber transmission systems. In this paper, we investigate theoretically and experimentally a method to generate in the optical domain stable chirp-free UWB signals with a narrow optical spectral width. The UWB pulse generator consists of a polarization modulator...
