Abstract

The simultaneous role of electrostatic effects and band‐mixing effects on optical modal gain in two coupled wells is analyzed within the self‐consistent solution of the Poisson and Luttinger–Kohn effective‐mass equations. The analysis is performed for a 1.3‐μm InGaAsP/InP lattice‐matched system. It shows that the electrostatic effects play a significant role in selecting the optimum barrier width and composition of the wells and barriers. The gain is actually larger when electrostatic effects are included because of better charge localization in the wells. © 2002 Wiley Periodicals, Inc.
