Abstract :
Optical free space transmission for terrestrial, inter- and intra-satellite communications offers the wireless advantages of RF systems, but with greater directivity, less crosstalk, and higher data rates. Semiconductor lasers used in these applications allow direct modulation which reduces optical components and overall transmitter size. We directly modulated a 980 nm laser diode and transmitted over 150 meters at a bit rate of 8 Gb/s. This represents the highest bit rate transmitted over such a free space distance
