Interplay between quantum Zeno and anti-Zeno effects in a nondegenerate hyper-Raman nonlinear optical coupler

Quantum Zeno and anti-Zeno effects are studied in an asymmetric nonlinear optical coupler composed of a probe waveguide system waveguide. The is operating under non-degenerate hyper-Raman process, while both the pump modes constantly interacting with effect presence on temporal evolution terms number photons Stokes anti-Stokes as well phonon quantified parameter. negative (positive) values parameter specific mode considered signatures quantum (anti-Zeno)effect that system. It observed phase mismatch generation processes can be controlled to induce transition between for off-resonant resonant process. However, case process waveguide, frequency detuning parameters also used analogously cause desired crossover. Further, general nature physical perturbative technique here allowed us analytically study possibilities observing large special cases, including situations where spontaneous, partially spontaneous and/or operated degenerate or simple Raman
