We have investigated feedback effects inducing frequency chirp by developing a model treating the ILM as a whole and obtained analytical expressions of the FM and AM responses. The variation of the frequency chirp with the residual facet reflectivity of the modulator section is calculated. The model predicts the unusual peak in the measured frequency responses and has been used to define design rules.336-340engDiffraction gratingsDistributed feedback lasersElectric currentsFrequency responseLight absorptionLight modulatorsLight propagationMathematical modelsOptical fiber couplingOptical linksRefractive indexBragg propagation constantCurrent intensityFrequency chirpGrating coupling coefficientIntegrated laser modulatorIntegrated optoelectronicsArtigo10.1109/2944.577390Acesso restrito2-s2.0-0030156721
