Thanks Damian Marek for ur kind response !
Sorry for confusion, i make it clear now,
1. The file i have attached above (and again attaching below) is showing modulation of Input sine signal with Optical Carrier through EAM, in result we are getting modulated optical pulses with time period of 7.8125 nsec and pulse width of 1.22 nsec.
At the output, optical pulse power changes from min value to max value when reaches peak. similarly at the input sine signal, amplitude changes from min to max value.
So when i make a 2D graph between “input sine signal amplitud” at x-axis and “output optical power” at y-axis then i got a “straight line” which should not be like that.
Because at the modulator output, optical pulse power changes and at the input sine signal amplitude changes therefor it is not possible to have a straight line in a graph.
SO i want to know y i am getting straight line ?
2. hw can i modify it ?
3. and how can i get a tranfer function of EAM in which i get a random behavior of input sine signal amplitude and output optical power ?
Hope u understand it now….
(Leave my 2nd comment above, in which i asked to use DC bias for another scenario. i wil explained it later)
I wil be very thakful to u for ur ths act of kindness.
best regards
best wishes.
