We compare three different approaches for low cost all-optical swapping of spectral amplitude code labels for packet-switched networks. The first uses cross-absorption modulation in an electroabsorption modulator within a semiconductor fiber ring laser (SFRL), the second uses cross-gain modulation (XGM) in a semiconductor optical amplifier (SOA) within an SFRL, and the third makes use of XGM in an...
All-optical swapping of spectral-amplitude code (SAC)-labels in a semiconductor fiber ring laser (SFRL) using cross-absorption modulation (XAM) in an electro-absorption modulator (EAM) is demonstrated. The wavelength and time domain representation of a packet using SAC-labels are obtained. The static transfer functions and spectral plots of the ON/OFF states for label-swapping from a single tunable...
Mode-locked fiber lasers have numerous applications in optical communications, sensing, and instrumentation. Semiconductor fiber lasers (SFLs) which are mode-locked via cross-gain modulation (XGM) and/or cross-phase modulation in a semiconductor optical amplifier (SOA) can also be used for all-optical clock recovery (AOCR). AOCR has been demonstrated in erbium-doped fiber lasers that are mode-locked...
