Main Module


Simulation of the signal-to-noise ratio (SNR) of a direct detection receiver. The variance of shot noise and thermal noise are first calculated and then SNR is calculated for a PIN photodiode.

Explore Further this Module:

5.1 Plot the SNR as a function of received power for different values of the load resistance R_{{L}}Explain the dependence of SNR on R_{{L}}.
5.2 Change the bit rate from 10 Gb/s to 40 Gb/s. Plot the SNR as a function of bit rate for a fixed value of received power. Why does the SNR decrease as the bit rate increases?

5.3 Modify this code to calculate the SNR of APD receivers.
