On the design of polarization‐insensitive semiconductor optical amplifiers

Abstract

We have used the 4 × 4 Luttinger–Kohn Hamiltonian to analyse the presence of delta‐strain in quantum well on the polarization properties of semiconductor optical amplifiers. The analysis is performed for a 1.55 μm InGaAsP/InP lattice matched system grown in the [001] direction with and without the electrostatic effects of the carrier charges. The importance of electrostatic effects is indicated. © 2002 Wiley Periodicals, Inc. Microwave Opt Technol Lett 35: 227–230, 2002; Published online in Wiley InterScience (www.interscience.wiley.com).
