摘 要
作为一个完整的光通讯系统，光发送机是它的一个重要组成部分，它的作用是将电信号转变为光信号，并有效地把光信号送入传输光纤。光发送机的核心是光源及其驱动电路。现在广泛应用的有两种半导体光源：发光二级管（LED计数器电路）和激光二级管（LD）。 在高速光纤通信系统中，Mach-Zehnder熔铜炉集成光波导电光调制器作为一种信号源的外调制器，它可以获得很窄的调制信号谱宽，降低光纤散的影响。此外，Mach-Zehnder集成光波导电光调制器调制速率高，能很好的满足光纤通信系统向更高速率发展的要求。这些特点令它成
为当前大容量光纤传输网络和高速光电信息处理系统中的关键器件，并有着广阔的发展前景。
本毕业设计主要完成的内容：基于optisystem的光纤通信系统中的光发送机设计，它的作用是将电信号转变为光信号，有效地把光信号送入传输光纤, 并详细讨论了影响啁啾参数的因素。导出了Mach-Zehnder结构外调制方式调制器的啁啾参数表达式组织芯片,研究表明该结构调制器频率啁啾不为零,而且调制器的直流偏置漂移对啁啾的影响很小。

ABSTRACT
As a complete optical communication system, optical transmitter is an important part of it, it is the role of the electrical signals into light signals, and effectively put the light signal into the transmission fiber. The core of an optical transmitter is the source and driving circuit. Now widely used two kinds of semiconductor light source: light emitting two tubes (LED) and laser diode (LD) .
In high-speed optical fiber communication system, Mach-Zehnder integrated optical waveguide electro-optic modulator as a signal External modulator source, it can obtain the modulation signal is very narrow spectral width, reducing the effect of fiber dispersion. In addition,Mach-Zehnder integrated optical waveguide electro-optic modulator modulation rate is high, can be very good to meet the fiber optical communication system High speed development requirements. These features make it become large capacity optical fiber transmission network and high speed optical telecommunication the key devi
ce, information processing system, and there are broad prospects for development.
