Hi Damian,
u have shared gud point in ur above comments. But there are some ambiguities as follow.
1. in Laser Measured project i have used default values of bias current and modulation peak current that are 23mA and 28mA respectively while threshold current and refrence current were 18mA and 23mA respectively (all were default values). So is that wrong ?
2. Damien, problem is that if i get proper Bias point still i am not sure wether it is exact point or not because i have no non linear graph from which i can verify exact bias point.
a. Further, I always get number of side bands at almost all values of Bias point during modulation but still lacks confidence on weather it is ture bias point or not.
And that is what i need here in this scenario of direct modulation for getting totl 7 bands (three on both side of center band).
b. Kindly share any method from which i can verify proper bias point, if u know …??
3. Damien can u share ur settings of getting proper Bias point of direct Modulation using either laser measured component or directly modulated laser in Figures so that we i can understand it and become able to get proper bias point and 7 bands output ??
It wil be so nice of u if u share figures of ur setting for proper biase point. kindly keep 128Mbit/sec bit rate for this scenario.
I will be very thakful to u for ur this kindness.
Best Regards
