“…The study of waveguide couplers that contain nonlinear materials have triggered great interest in the integrated optics [35][36][37][38][39][40][41][42] and are critically essential for the implementation in future quantum computers [42] due to their novel all-optical switching applications [40,41] since being introduced by Jensen in 1982 [43]. It has been demonstrated that light propagation (light transfer, light split, light return, etc.)…”

We investigate the adiabatic evolution of light in nonlinear waveguide couplers via resonancelocked inverse engineering based on stimulated Raman adiabatic passage (STIRAP). The longitudinal varying detunings of the propagation coefficients are designed to eliminate dynamically the nonlinear effect, which induce the non-adiabatic oscillations. We show that different light evolutions such as complete light transfer, light split and light return can be realized adiabatically with appropriate choices of the detunings even in the nonlinear regime. The features open new opportunities for the realization of all-optical nonlinear devices with high fidelity in integrated optics.

“…The phase space approach is the first, while the analytical perturbative method is the second. Previously, the phase space method has been applied in several types of Raman scattering [15] and various designs of nonlinear couplers [16]- [18]. Meanwhile, the analytical perturbative method has been widely implemented in the system such as Bose-Einstein condensation [19], [20], optomechanical-like system [21]- [23], light-semiconductor interaction [24], Raman process [25]- [28] and nonlinear coupler as well [12].…”

Squeezed states of light in a three-channel nonlinear coupler with second-order nonlinearity using the phase space method and the analytical perturbative method is reported in this paper. The system is studied under the frequency mismatch condition, where the frequencies of the pump mode are not common. The effect of frequency mismatch on the generated squeezed states is investigated. We have found that the frequency mismatch does significantly affect the behavior of the generated squeezed states only at higher values of linear coupling between the waveguides. By increasing the frequency mismatch, the squeezing pattern also evolves from a collapses-revivals-like squeezing into a constant oscillation.
