    "abstract": "Entanglement of the excitonic states in the system of two coupled\nsemiconductor microcrystallites, whose sizes are much larger than the Bohr\nradius of exciton in bulk semiconductor but smaller than the relevant optical\nwavelength, is quantified in terms of the entropy of entanglement. It is\nobserved that the nonlinear interaction between excitons increases the maximum\nvalues of the entropy of the entanglement more than that of the linear coupling\nmodel. Therefore, a system of two coupled microcrystallites can be used as a\ngood source of entanglement with fixed exciton number. The relationship between\nthe entropy of the entanglement and the population imbalance of two\nmicrocrystallites is numerically shown and the uppermost envelope function for\nthem is estimated by applying the Jaynes principle.",
