| Abstract: | A useful technique for evaluating the chirp parameter α of electroabsorption modulators is presented. The α parameter of a GaInAs/GaInAsP quantum-well (QW) electroabsorption modulator integrated with an active segment in a Fabry-Perot cavity has been evaluated by measuring the Fabry-Perot fringes. It has been shown that the relationship between absorption changes and refractive index changes is nonlinear and the α parameter is dependent on operating wavelengths |
