Abstract

Lithium niobate LiNbO/sub 3/ (LN) Mach-Zehnder interferometer (MZI) modulators are a key in high-speed optical communication systems. The optimization of integrated Mach-Zehnder interferometer modulator is discussed in this paper. We have extensively characterized the drift phenomena in a typical MZI modulator as a function of time, temperature and optical power. We have carried out optical and electrical measurements of the characteristics of the passive component and the active component as well. We also took into account of other physical properties such as pyroelectric effect, photovoltaic effect and photoconductivity. The electrical characteristics of the wafer and component were investigated and reported here. We present here the first results of the simulations which were obtained in this frame. These predictions are then compared with the effective electric field in the different layers and its time behavior.

集成马赫-曾德尔干涉仪调制器的优化:电学和光学研究
铌酸锂LiNbO/ sub3 / (LN)马赫-曾德尔干涉仪(MZI)调制器是高速光通信系统中的关键器件。本文讨论了集成马赫-曾德尔干涉仪调制器的优化问题。我们广泛地描述了典型MZI调制器中的漂移现象是时间、温度和光功率的函数。我们还对无源元件和有源元件的特性进行了光学和电学测量。我们还考虑了其他物理性质,如热释电效应、光伏效应和光电导率。本文对晶圆和元件的电特性进行了研究和报道。本文给出了在此框架下得到的初步模拟结果。然后将这些预测结果与不同层的有效电场及其时间行为进行比较。
