Title: Complete and robust energy conversion by sum frequency generation based on Invariant Engineering
Authors: Congfu Zhang, Zhaolu Wang and Hongjun Liu
Abstract summary: We propose an analytical method to achieve complete energy conversion in sum frequency generation based on Lewis-Riesenfeld invariants theory. It is demonstrated that the frequency conversion can be achieved in the wavelength range of 2.6 mum -3.6 mum with a spectral bandwidth of the conversion efficiency over 50% approaching to 400 nm when the crystal length L=1 mm.

Abstract: We propose an analytical method to achieve complete energy conversion in sum frequency generation based on Lewis-Riesenfeld invariants theory. This technique, derived from a two-level atom transition in quantum mechanics, is more efficient and robust than conventional methods. In our scheme, the quasi-adiabatic single control parameter model is established, and the value of single control parameter is selected to make the initial eigenstate perfectly converted to the final eigenstate we need. Corresponds to the nonlinear frequency conversion process, the nonlinear crystal structure is designed with the inverse engineering of optimal control theory, which is robust against the perturbations in the coupling coefficient and phase mismatch, including pump intensity and crystal polarization period variations, and results in almost 100% conversion efficiency at any crystal length. It is demonstrated that the frequency conversion can be achieved in the wavelength range of 2.6 {\mu}m -3.6 {\mu}m with a spectral bandwidth of the conversion efficiency over 50% approaching to 400 nm when the crystal length L=1 mm.

Frequency conversion in a hydrogen-filled hollow-core fiber: power scaling, background, and bandwidth [0.0]
Large-area quantum networks based on optical fibers allow photons at near-infrared wavelengths to travel with minimal loss. Quantum frequency conversion is a method to alter the wavelength of a single photon while maintaining its quantum state. Most commonly, nonlinear crystals are employed for this conversion process, where near-unity conversion efficiency at high fidelity has been demonstrated.
