We calculated the wavefunction and the binding energy of the biexciton in semiconducting carbon nanotubes and studied the spectral weights of the photoluminescence spectra and the biexciton contribution to the two-photon absorption spectra. The wavefunction and the binding energy are calculated by means of the the Lanczos method.
