Abstract

All-optical synchronization and timing extraction based on self-pulsating twin section lasers are demonstrated. The variation of the unlocked full-width-at-half-maximum (FWHM) of the fundamental of the RF spectrum of a self-pulsating laser diode is investigated. It is shown for the first time that the variation of the FWHM with frequency is dependent on the slope of the absorber bias versus self-pulsation frequency characteristic. The results have important implications for the design and selection of self-pulsating laser diodes for synchronization applications.<>
