Abstract
We use an idealized band structure to compare the characteristics of tensile‐ and compressive‐strained quantum‐well lasers. We show that although the threshold carrier density increases as expected in tensile‐strained lasers, both the radiative current density and differential gain can be comparable to or improved over compressively strained lasers.This publication has 13 references indexed in Scilit:
