Abstract Using the envelope function approximation and a one band model, the absorption coefficient of a quantum wire with arbitrary transverse section is studied. The selection rules for direct allowed transitions are reported. The results are particularised for the cylindrical case with infinite potential barrier, and numerical results for GaAs are given.
