Photonic switching of RF signals based on optical single sideband (OSSB) wavelength conversion using a semiconductor optical amplifier (SOA) for radio-over-fiber applications is proposed and demonstrated. The scheme realizes OSSB signal generation simultaneously with the photonic microwave switching based on self-phase modulation (SPM), cross-gain modulation (XGM) and four-wave mixing (FWM) effects...
In the future broadband wireless access networks, many remote antenna units (RAUs) are required to connected to a center office. To differentiate each RAU, wavelength-division multiplexing (WDM) is an efficient and mostly-used way, but this would require expensive wavelength-specific or wavelength-tunable optical sources. To reduce the cost, colorless or wavelength-independent RAU is highly desirable...
A novel bidirectional radio-over-fiber system is proposed and demonstrated based on the cross-polarization modulation (XPolM) and the cross-gain modulation (XGM) effects in a semiconductor optical amplifier (SOA). With a polarization beam splitter (PBS) placed at the remote antenna unit, the polarization modulation induced by the SOA is converted into two complementary (namely, non-inverted and inverted)...
We propose and demonstrate a novel single-longitudinal-mode dual-wavelength erbium-doped fiber ring laser incorporating a semiconductor optical amplifier. The dual-wavelength output with 40-GHz wavelength spacing is switchable in the range of 1533 nm-1565 nm.
