Optical analysis of multiple-quantum-well lasers
Abstract
Computational results are presented on a multiple-quantum-well laser consisting of six active GaAs layers separated by five undoped Ga(1-y)Al(y)As layers and enclosed between p- and n-type Ga(1-x)Al(x)As cladding layers. It is shown that a three-region waveguide with identical cladding layers, a center layer of the same total thickness, and an averaged refractive index will have virtually the same effective modal index, near field, far field, and confinement factor of the multiple-quantum-well laser from which it is derived when the structure and model waveguide support only the fundamental mode.
