我们报告的实验和建模结果的非线性动力学的谐振隧穿二极管（RTD）的光电电路，可用作无线接入网络的无线/光接口的基础。基于RTD的电路是具有负差分电阻的光电集成电路，并且充当光电压控振荡器。这些电路显示了许多经典非线性动力学的特征，包括混沌和同步。这些高度非线性振荡器表现为注入锁定振荡器，其可以通过无线或光学源的小注入信号来同步，并且因此可以将相位编码信息从无线传输到光学域或从光学传输到无线域。
We report on experimental and modeling results on the nonlinear dynamics of a resonant-tunneling-diode-based (RTD) optoelectronic circuits that can be used as the basis of a wireless/optical interface for wireless access networks. The RTD-based circuits are optoelectronic integrated circuits that have negative differential resistance and act as optoelectronic voltage-controlled oscillators. These circuits display many of the features of classic nonlinear dynamics, including chaos and synchronization. These highly nonlinear oscillators behaves as injection-locked oscillators that can be synchronized by a small injection signal of either wireless or optical origin, and thus, can transfer phase encoded information from wireless to the optical domain or the optical to the wireless domain.
