نویسندگان
چکیده
: In this paper investigation has been done on two different photodiodes PIN and APD for use as a receiver in free space fiber optical link. Eye Diagrams have been used to evaluate value of Qfactor in each and every case. Gaussian pulse modulation format has been used in this analysis work. It is clear from the findings of this analysis that value of Q-factor is maximum when APD has been used as the receiving photodiode at 1550nm wavelength and minimum when PIN diode has been used as receiving photodiode at 1550nm wavelength. Keywords-: PIN, APD, Gaussian pulse modulation, free space optical link, Qfactor

Incremental adaptive networks implemented by free space optical (FSO) communication
The aim of this paper is to fully analyze the effects of free space optical (FSO) communication links on the estimation performance of the adaptive incremental networks. The FSO links in this paper are described with two turbulence models namely the Log-normal and Gamma-Gamma distributions. In order to investigate the impact of these models we produced the link coefficients using these distribu...

متن کاملBit-error rates for optical receivers using avalanche photodiodes with dead space
Bit-error rates are computed for an on-off keying optical communication system using avalanche photodiodes (APD’s). We use a model for the APD that includes dead space and the finite response time. Dead space is the minimum distance that a newly generated carrier must travel in order to acquire sufficient energy to become capable of causing an impact ionization in the multiplication region of t...
متن کاملRecent Advances in Ultra-High-Speed Waveguide Photodiodes for Optical Communication Systems
This paper describes the recent advances in semiconductor photodiodes for use in ultra-high-speed optical systems. We developed two types of waveguide photodiodes (WG-PD) — an evanescently coupled waveguide photodiode (EC-WG-PD) and a separated-absorption-andmultiplication waveguide avalanche photodiode (WG-APD). The EC-WGPD is very robust under high optical input operation because of its distr...
