摘　　要：This paper reports on the design,fabrication,and performance of an integrated electro-absorptive modulated laser based on butt-joint configuration for 10Gbit/s application.This paper mainly aims at two aspects.One is to improve the optical coupling between the laser and modulator;another is to increase the bandwidth of such devices by reducing the capacitance parameter of the modulator.The integrated devices exhibit high static and dynamic characteristics. Typical threshold current is 15mA,with some value as low as 8mA.Output power at 100mA is more than 10mW.The extinction characteristics,modulation bandwidth,and electrical return loss are measured.3dB bandwidth more than 10GHz is monitored.报道了用于10Gbit/s传输的DFB激光器和EA调制器对接集成器件的设计、制作和器件特性.工作主要集中于两个方面:提高激光器和调制器间的光学耦合;通过减小调制器电容提高调制带宽.集成器件显示出了良好的静态和高频特性:阈值电流典型值为15mA,最小值为8mA;100mA激光器偏置电流下,输出功率大于10mW;对消光比、电学回波损耗和调制带宽进行了测试,3dB带宽的测量值超过10GHz.
