Robust BPSK Impulse Radio UWB-over-Fiber Systems Using Optical Phase Modulation
Coherent communications Radio frequency photonics
2015/5/22
The impact of fiber dispersion on the performance of optical phase modulated impulse-radio-ultrawideband (IR-UWB) signals is experimentally investigated. 2Gbps BPSK IR-UWB over 78km fiber transmission...
40 Gb/s Carrierless Amplitude and Phase Modulation for Low-Cost Optical Datacommunication Links
Fiber optics communications Modulation
2015/5/22
4 bps/Hz 40 Gb/s carrierless amplitude and phase (CAP) modulation is investigated for next-generation datacommunication links. The 40 Gb/s link achieves double the length of a conventional NRZ scheme,...
Continuous Phase Modulation as an Alternative to QPSK for 100 Gb/s Optical Links
Fiber optics communications Coherent communications
2015/6/5
Constant envelope formats including CPM may reduce the impact of nonlinear impairments arising from intensity variations and the associated nonlinear phase noise. We quantify the advantages of CPM ver...
Polarization Insensitive All-Optical Retiming Based on Cross-Phase Modulation and Offset Filtering with Distributed Raman Amplification
Polarization Insensitive All-Optical Retiming Based Cross-Phase Modulation Offset Filtering Distributed Raman Amplification
2015/7/31
Adding distributed Raman amplification to a polarization insensitive all-optical retiming technique based on cross-phase modulation and offset filtering reduces the timing jitter of 10 Gb/s retimed si...
