25G可调激光器芯片带宽数据

可调谐激光器的外调制芯片3dB带宽测试，是使用矢量网络分析测量可调谐激光器的外调制芯片的3dB带宽性能。3dB带宽指通过可调谐激光器的外调制芯片的信号幅值变成输入幅度的二分之根号二倍时对应的频率带宽，信号幅值的平方即为功率，平方后变为二分之一倍，在对数坐标中就是-3dB的位置，也就是半功率点，对应的带宽就是输出功率在减少至一半以前的频率带宽，3dB带宽表示在该带宽内集中了一半的功率。The 3dB bandwidth test of the external modulation chip for tunable lasers aims to characterize the 3dB bandwidth performance of such external modulation chips using vector network analysis. The 3dB bandwidth is defined as the frequency bandwidth at which the amplitude of the signal passing through the external modulation chip of a tunable laser drops to √2/2 of the input amplitude. Since the signal power is the square of the amplitude, the corresponding power will be reduced to 1/2 of the original value after squaring, which corresponds to the -3dB point in the logarithmic coordinate system (i.e., the half-power point). The 3dB bandwidth refers to the frequency range before the output power decreases to half of the initial value, and it indicates that half of the total signal power is concentrated within this bandwidth.
