Abstract:A single-mode distributed-feedback (DBF) laser with a large side-mode suppression ratio was investigated to fulfill the single-mode assumption of the Lang-Kobayashi (LK) model. A single-mode 1.55-μm DFB semiconductor laser was subjected to delayed optical feedback from an external cavity. The spectra were recorded with a grating spectrometer with a resolution of 0.1 nm. The significant linewidth broadening toward longer wavelength corresponded to predictions of the LK model.
