  • Abstract
    A monolithically integrated distributed feedback laser with an electroabsorption modulator has been investigated showing a redshift of emission wavelength with applied modulator bias voltage. This leads to an adiabatic chirp parameter αH of up to 0.13 that is usually zero for decoupled devices like hybrid laser modulator integrations. By measurement and corresponding simulation, the phenomenon was identified to be caused by thermal coupling between the sections.
