Ultra-wide band signal generation using a silicon micro-ring resonator tuned to a NRZ-DPSK modulated optical carrier is proposed and demonstrated. Tuning of the coupling regions of the micro-ring enables the synthesis of monocycle pulses.
We demonstrate multi-channel regenerative NRZ-to-RZ conversions with tunable output pulse-width and single-to-dual function, using a phase-modulator and an AWG. Transmission and BER show a good performance for the converted RZ signal compared with conventional one.
A novel photonic generation of power-efficient ultra-wideband (UWB) pulse by combining two asymmetric monocycle pulses with inverted polarities is experimentally demonstrated. The principle lies in cross-phase modulation (XPM) in a single semiconductor optical amplifier (SOA) and phase modulation to intensity modulation conversions in an arrayed-waveguide grating (AWG). The Federal Communications...
We present optical ultrawideband doublet generation from NRZ-DPSK signals based on a length of SMF. The generated ultrawideband spectra using 25 km SMF and 15 km SMF are analyzed contrastively.
We theoretically discuss 40 Gb/s semiconductor optical amplifier (SOA)-based wavelength conversion (WC) using a detuning optical bandpass filter. Both inverted and non-inverted WCs are obtained by shifting the filter central wavelength with respect to the probe wavelength when input data signal is RZ format. The filter detuning is essential to different output formations
All-optical wavelength conversion (WC) based on transient cross-phase modulation (T-XPM) of semiconductor optical amplifier (SOAs) is a promising approach to accelerate the gain recovery of SOAs. An analytical solution is deduced to explain the polarity variation of WC based on T-XPM of SOAs from the viewpoint of the impulse response functions. We conclude that both inverted and noninverted WCs can...
