Abstract

一种光信号调制电路和装置，光信号调制电路包括激光器(DFB)、调制器(EAM)和运算放大器，其中激光器(DFB)产生激光激发调制器(EAM)产生光生电流(ip)，调制器(EAM)的第一端口(a)与第一输入电压(Vbias)连接，第二端口(b)与所述运算放大器的反向输入端连接；运算放大器与的同相输入端与第二输入电压(Vin)连接，运算放大器的输出端与调制器的第一端口(a)连接。该调制电路利用EAM的光生电流信号(ip)，反馈给运算放大器，实现第二输入电压(Vin)与EAM的光生电流信号(ip)成线性关系，获得线性的EML传输曲线，即高线性度的EML，大大降低调制过程中产生的光信号非线性失真，提高长距离光纤传输的质量。
