Analysis of the high bit-rate 1.55 /spl mu/m lightwave system with the limited P-i-N photodiode bandwidth

We analyze the impact of the limited P-i-N photodiode bandwidth on the performance of the 1.55 /spl mu/m IM/DD (Intensity Modulation/Direct Detection) 10 Gb/s digital optical communication systems. The complete model of the optical communication system with the special accent on P-i-N photodiode is described. The computer simulation based on the developed model shows that the limited P-i-N photodetector bandwidth reduces the overshoot of the filtered signal at receiver. The proper selection of the P-i-N photodiode non-material parameters may improve the quality of signal detection at receiver side.
