Hi Karan,

The Laser’s rise time is the time required for laser output from 10% to 90% of total power.

Rise time is a factor that decides the 3db Bandwidth of the Laser. ( risetime = 0.35/BW )

So, for rise time = 35 ps. The BW = 1 Gbps.

In the layout attached, I directly modulated the Laser above 1Gbps and the output of laser showed absolutely no distortion.

I tried this with the analog signals also, but the result is the same.
