Analysis of Novel Cascaded $\chi^{(2)}$(Sfg+Dfg) Wavelength Conversions in Quasi-Phase-Matched Waveguides
Abstract
A novel cascaded second-order nonlinear interaction $(\chi^{(2)})$, which is simultaneously based on sum frequency generation (SFG) and difference frequency generation (DFG) processes, is proposed and analyzed in quasi-phase-matched wavelength converters. Analytical expressions with clear physical insights are derived for the converted light. It is shown that the same conversion efficiency can be achieved by employing two pump sources with …
