Abstract
We study the process of sculpturing threewave weakly coupled states under the action of the pulsed optical pump in a twomode squarelaw nonlinear waveguide within the collinear regime of propagating the interacting waves. The analytical model for this process with slightly mismatched wave numbers predicts the sculpturing of multipulse optical components inherent in threewave coupled states. Reasoning from the developed approach, we discuss an opportunity for the digital modulation of light, because those potentially threewave coupled states under consideration can be binary encoded. The performed analysis of sculpturing multipulse coupled states in a nonstationary regime was experimentally examined during our studies of collinear acoustooptical interaction in a twomode lithium niobate waveguiding structure exhibiting a squarelaw nonlinearity.
Keywords: Threewave collinear interaction; optical pump; multipulse threewave coupled states; squarelaw nonlinearity.
Resumen
Se estudió el proceso para obtener tres estados débilmente ligados por bombeo óptico pulsado en una guía de ondas no lineal de variación cuadrática doble dentro del régimen colineal de propagación de ondas interactuantes. El modelo analítico para este proceso con números de onda en ligera discordancia predice este fenómeno. En base a lo anterior se discute la modulación digital de la luz debida a que, potencialmente, los tres estados acoplados bajo estudio pueden ser codifícaos en forma binaria. Se realizó el análisis experimental del fenómeno anterior a través del estudio de la interacción acustóptica colineal en una guía de ondas de niobato del litio y se observó un comportamiento cuadrático.
Descriptores: Interacción coolineal de tres ondas; bombeo óptico; estados acoplados de tres ondas; ley cuadrática.
