Two Photon Frequency Conversion

Abstract

We experimentally demonstrate mid-IR to visible frequency conversion via simultaneous two photon excitation, while the intermediate frequency remains dark throughout the process. The phase mismatch in such mechanism is shown to be intensity dependent.

Efficient two-process frequency conversion through a dark intermediate state

Gil Porat, Ady Arie

Two simultaneous three wave mixing processes are analyzed, where an input frequency is converted to an output frequency via an intermediate stage. By employing simultaneous phase-matching and an adiabatic modulation of the nonlinear coupling strengths, the intermediate frequency is kept dark throughout the interaction while obtaining high conversion efficiency. This feat is accomplished in a manner analogous to population transfer in atomic stimulated Raman adiabatic passage. Applications include conversion between remote frequencies, e.g., mid-IR to visible, and study of electronic crystal properties in the UV absorption band.

Efficient Three-Process Frequency Conversion Based on Straddling Stimulated Raman Adiabatic Passage

Chao Sun, Changshui Chen, Junxiong Wei +1 more

The high-efficiency three-process frequency conversion is analyzed. By analysis of coupling equations, the optical straddling stimulated Raman adiabatic passage (S-STIRAP) scheme is proposed. Numerical simulation shows that the input power of the first frequency is monotonically converted into the output power of the last frequency, with the intermediate frequencies kept extremely low along the interacting length. We expect that this frequency conversion scheme has application in the frequency conversion between highly disparate frequencies, e.g., mid-IR to visible.
