Abstract :
The static wavelength shift for multielectrode distributed-feedback laser diodes (DFB LDs) with a λ/4-phase-shift is studied using a two-dimensional numerical simulation program. This program gives a self-consistent carrier distribution and the corresponding refractive index distribution under nonuniform carrier injection. Accordingly, it aids understanding of the wavelength shift related to spatial hole burning. The wavelength shift and spatial hole burning effects for a multielectrode DFB LD are studied under various operating conditions and electrode lengths. It is demonstrated that the previously proposed wavelength and shift model for a single-electrode DFB LD is a universal model for a multielectrode DFB LD
