Structural and strain effects on the maximum modulation bandwidth are analyzed for quantum‐well lasers operating at 1.55 μm using the K factor method. Maps of frequency bandwidth for different values of Ga and As concentrations were created. Our results suggest that larger modulation bandwidth can be obtained for compressive strain than for tensile strain. ©1996 John Wiley & Sons, Inc.
