Calculate the receiver sensitivity (at a BER of 10−9) for the receiver in Problem 4.12 in the shot-noise and thermal-noise limits. How many photons are incident during bit 1 in the two limits if the optical pulse can be approximated by a square pulse?
A 1.3-µm digital receiver is operating at 100 Mb/s and has an effective noise bandwidth of 60 MHz. The p–i–n photodiode has negligible dark current and 90% quantum efficiency. The load resistance is 100 Ω and the amplifier noise figure is 3 dB. Calculate the receiver sensitivity corresponding to a BER of 10 −9. How much does it change if the receiver is designed to operate reliably up to a BER of 10−12?
