Paper Abstract

We have carefully observed on the spectral characteristics of two-segment 1.55 micrometers InGaAsP/InP ridge waveguide multi-quantum-well DFB lasers and found two types of wavelength switching. The first type occurs between the longitudinal-modes on the opposite sides of the DFB stopband, while the second type on the same side of the stopband. The physical mechanism is correlated to a slight difference of the effective grating period between the two inhomogeneously injected laser segments.
