Biexcitonic Nonlinearity in Quantum Wires
The peculiarities of the quasi-one-dimensional exciton and biexciton are analyzed theoretically. The calculated binding energies and wave functions are used within a simple boson model to predict biexcitonic optical nonlinearities to be expected in GaAs/GaxAl1−x Quantum Well Wires. The results are compared to the corresponding ones in Quantum Wells and bulk semiconductor. An assessment of inhomogeneous line broadening due to a Gaussian distribution of quantum well wire radii is also presented.
