Abstract

One distributed feedback (DFB) laser diode with main and multiple side modes injection-locked is proposed and demonstrated. DFB laser diode can be successfully injection-locked not only in the main mode but also in the side modes. The side mode suppression ratio (SMSR) value of each injection-locked mode is enhanced, thereby, it can be a promising candidate for the use of multiple optical sources. Our proposed scheme has the potential to be used as optical sources for radio-on-wavelength division multiplexing (WDM) transport systems to provide multiple services.
