Lossless beam splitter has been studied by the exact diagonalization o
f the homodyne photocurrent. The probability of totally symmetric and
totally antisymmetric output from a balanced beam splitter fed by arbi
trary number states has been evaluated. Efficiency of photon mixing to
synthesize highly excited number states has been also discussed.
