Nothing Travels Faster Than Light
... So, by propagating a wave through such a region it is possible to achieve a group velocity that is greater than the speed of light. But in previous attempts to demonstrate this, which were usually carried out with opaque media, the pulse or wave-packet was severely absorbed and distorted as it passe ...

Performance evaluation of the free space optical (FSO)
... These receivers are used when information is modulated onto the optical carrier using AM, FM, or PM, and are essential for FM or PM detection. The detection of optical fields is effected by various noise sources present at the receiver. The three dominant sources in FSO communications are: backgroun ...

Application scenarios for optical OFDM
... With the revival of coherent detection the fiber-optic community is seeing a rapid acceleration in transponder technologies. Next generation systems are evolving to dynamically reconfigurable optical networks with capacities of up to 10 Tb/s. However, the question remains: What comes next? One poten ...
