Summary :

The single fundamental transverse mode condition, both in three-layer DH, and asymmetrical five-layer separate confinement heterostructure (SCH) laser diodes operating at 1.55 µm wavelength, has been investigated based on the effective refractive index. The simple derived formula can be applied to obtain the effective refractive index of the dominant mode in DFB laser diodes to determine the corrugation period corresponding to the designed wavelength.
