Abstract

Distributed feedback (DFB) laser parameters such as grating coupling coefficient, effective indices, facet reflectances, and the phases of facet reflectances have been determined using a method based on least-square fitting of theoretical spectra to measured, subthreshold DFB laser emission spectra, The only inputs needed are geometrical parameters such as length, grating period, and internal grating phase shifts. Alarger number of devices have been successfully characterized, and consistent results have been obtained in both 1,3-mu m multi-quantum-well (MQW) DFB lasers with both facets as-cleaved, and in 1.55-mu m MQW DFB lasers with no, one, or two facets as-cleaved.
