提出了一种通过减少非线性和色散引起的载波抑制来提高模拟光传输性能的新技术。利用半导体光放大器（SOA）的增益饱和特性降低了马赫-曾德尔调制器（MZM）的固有非线性失真分量。在二次偏置点处，MZM的复合三拍（CTB）降低了9 dB，动态范围随之提高了4.5 dB。半导体光放大器（SOA）的负啁啾特性降低了传输长度和工作频率对射频载波的抑制，并通过SOA的线性化实现了传输后CTB的增强。
A novel technique to improve an analog optical transmission performance by reducing both the nonlinearity and chromatic dispersion induced carrier suppression has been proposed. The intrinsic nonlinear distortion component of Mach-Zehnder modulator (MZM) was reduced by gain saturation characteristics of semiconductor optical amplifier (SOA). The composite triple beat (CTB) of MZM was reduced as much as 9 dB at the quadratic bias point and the following enhancement of dynamic range by 4.5 dB was obtained. The RF carrier suppression for the transmission length and operating frequency was reduced by a negative chirp characteristic of semiconductor optical amplifier (SOA) and the enhancement of CTB after transmission were also achieved as a result of the linearization using SOA.
