Abstract : Abstract – Owing to the high commercial demand for optical communication system, the fundamentals of avalanche photodiode (APD) and photodiode intrinsic negative (PIN) of receiver performance have received extensive attention. This work presents a performance analysis and comparison of APD and PIN photo detectors using optical wireless communication channel. Many parameters are investigated to study the effects of input power, extinction ratio, gain, thermal noise, bandwidth, and dark current. Results show that APD photodiode shows high Q-factor, which is mainly affected by gain and thermal noise, whereas PIN photodiode is influenced by thermal noise. Moreover, the APD’s gain acts anessential role, and the shot noise has to be carefully dealt with. The implementation of APD photodiode in optical communication system exhibited high Q-factor of 257 for long transmission distance of up to 300 km compared to PIN photodiode with Q-factor of 219. Furthermore, the correlation of receiver sensitivity with extinction ratio and thermal noise is examined and compared. Keywords - OWC channel, PIN, APD, Q-factor, thermal noise, shot noise, gain, extinction ratio.
