自發性震盪雷射二極體在外加正弦驅動下之非線性動力系統

Abstract

一種高維度的自發性震盪雷射二極體，在外加正弦驅動下，能顯示出兩個競爭頻率的非線性動力系統。藉由增加電流調節，可以建立達到渾沌的路徑。然而，藉由改變頻率調節，自發性震盪頻率之調和頻率的渾沌狀態會突然消失。這個方法在可能性光學渾沌傳訊上，提供了簡單的渾沌光源。

A high-dimensional self-pulsating laser diode under an external drive shows the nonlinear dynamical effects of two competing frequencies. Route to chaos can be established by increasing the modulation current. However, by the varying the modulation frequency, the chaotic state is suddenly destroyed at the harmonic frequencies of the self-pulsating frequency. This approach offers a simple chaotic light source for possible optical chaotic communication.
