چکیده
Indoor free space optical (FSO) communication technology that provides high-speed connectivity to edge users is expected be introduced in the near future mobile system, where silicon photonics solid-state beam scanning device a promising tool because of its low cost, long-term reliability, and other beneficial properties. However, current two-dimensional devices using grating coupler arrays have difficulty increasing transmission capacity bandwidth regulation. To solve problem, we broadband surface coupler, “elephant coupler,” which has great potential for combining wavelength spatial division multiplexing technologies into device, as an alternative couplers. The prototype port-selective fabricated 300 mm CMOS pilot line achieved emission with 1 dB-loss 40 nm demonstrated imaging lens. also exhibited free-space signal non-return-to-zero on-off-keying signals at 10 Gbps over wide range 60 nm. In this paper, present overview developed device. Furthermore, theoretical design guidelines indoor FSO are discussed.

Development of Free Space Optical Link for Broadband Data Communication
To transfer high speed data streams, a line of sight (LOS) broadband free space optical (FSO) communication link has been designed between two private local LANs located at an aerial distance of about 2 km. A laser diode (LD) – avalanche photodiode (APD) combination operating at 1550nm is used to work as an optical trans-receiver system while an Erbium-doped optical amplifier (EDFA) is used to ...
متن کاملIncremental 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 کاملBeam width and transmitter power adaptive to tracking system performance for free-space optical communication.
The basic free-space optical communication system includes at least two satellites. To communicate between them, the transmitter satellite must track the beacon of the receiver satellite and point the information optical beam in its direction. Optical tracking and pointing systems for free space suffer during tracking from high-amplitude vibration because of background radiation from interstell...
