- Abstract
The photon pair generation (PPG) via spontaneous four-wave mixing (SFWM) in an optically excited third-order nonlinear cavity forms large-scale high-dimensional quantum states, called quantum frequency combs (QFC). The scalable practical generation and control of these photonic states via integrated devices enable quantum information processing for applications in secured communications and quantum computing [1]. Modifying the excitation field properties in different degrees of freedom, e.g., polarization [2], frequency or spatial modes [3], allows controlling the structure of the generated quantum state by favoring different types of SFWM processes. In this work, by using two excitation fields and varying their intensity, P1 and P2, respectively, we demonstrate the occurrence of two different SFWM processes (degenerately and non-degenerately excited SFWM) and a control of the pair generation rate: µ(r, P) = µ1(P1(r, P)) + µ2(P2(r, P)) + µND(r, P), where P is the total excitation power, r = P1/P is the power ratio, µ1, µ2 describe the degenerate process and µND the non-degenerate process.
