Combinatorial optical complex wavelet-fractional Fourier transform.

Abstract

By using the technique of integration within ordered product of operators, we put forward the combinatorial optical complex wavelet-fractional Fourier transform in the context of quantum optics. The unitary operator for this new transform is found and its normally ordered form is deduced. We apply this new transform to the two-mode vacuum state and the two-mode number state and explain that it can be used to analyze and identify various quantum optical states.
