Abstract
Analyzing the environmental response to high-power optical waves radiated into a quantum frequency converter is our aim of the paper. We examine the non-classical properties of the electromagnetic waves emitted from this system, using a fully quantum description for this nonlinear optical system. With the help of rotating wave approximation and solving the Heisenberg equations of motion for signal (strong) and idler (weak) frequencies, we study the non-classical properties of the produced output waves, including squeezing, entanglement and quantized field antibunching. Analytical and numerical results evidently confirm that most of these non-classicality signs can be revealed for the composite number and pair coherent states, as the entrance waves to the quantum frequency converter, distinctly.
