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 *** paper mainly aims at two *** 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 *** integrated devices exhibit high static and dynamic characteristics. Typical threshold current is 15mA,with some value as low as *** power at 100mA is more than *** extinction characteristics,modulation bandwidth,and electrical return loss are measured.3dB bandwidth more than 10GHz is monitored.
