THE RELATIONSHIP BETWEEN CHAOS AND GAIN IN TERMS OF INTERMODULATION DISTORTION

16638

In this study, four-tone small signal analysis is performed for non-linear optoelectronic feedback laser diode system. In the analysis, after expanding the Volterra power series up to second-order, the second kernel (Z2) for the output intermodulation distortion (IMD) analysis is performed. The components which are 1.(ω0 + ω1),(ω0 - ω1) ,2. (ω0 +ω2), (ω0 -ω2),3. (ω0+ ω3), (ω0 - ω3) and 4. (ω0 + ω4), (ω0- ω4) among the alternative IMD frequencies are selected for the analysis. The amplitudes of the selected IMD frequency components are analysed depending on the time delay constant ( t 0) and the feedback gain constant (K). The critical frequencies (coherence collapse, chaos), and the critical feedback values are also determined.
