Abstract:
Using a stimulated parametric down-conversion processcombined with a conventional detector, we theoretically propose ascheme to realize the stimulated emission-based detector, andinvestigate the antinormally ordered correlation function and Fanofactor for the coherent field based on it. Such a detection hasadvantages over the normally ordered one especially when theintensity of the field is weak.
