Embodiment Construction

[0060] One or more implementations of the current subject matter can provide improved optical propagation efficiency for free-space optical wireless optical communication systems operating within the C-band wavelength spectrum. These efficiencies can be achieved in a reduced optical attenuation coefficient reduction along with significantly improved scintillation performance characteristics when compared to current FSO communication systems operating in the 1550nm C-band.

[0061] Typically, using FSO in conjunction with high power optical amplification techniques can often achieve only marginal increases in optical budget and system availability, especially during fog-related events, during which optical attenuation in the transmit band can rise to 100dB / km and higher. A common limitation to system performance for currently available 1550nm FSO systems, and also to systems operating at shorter optical operating wavelengths, is the wavelength sensitivity of attenuation due to ...

Abstract

Enhancements in optical beam propagation performance can be realized through the utilization of ultra-short pulse laser (USPL) sources for laser transmit platforms, which are can be used throughout the telecommunication network infrastructure fabric. One or more of the described and illustrated features of USPL free space-optical (USPL-FSO) laser communications can be used in improving optical propagation through the atmosphere, for example by mitigating optical attenuation and scintillation effects, thereby enhancing effective system availability as well as link budget considerations, as evidenced through experimental studies and theoretical calculations between USPL and fog related atmospheric events.

Description

[0001] Cross References to Related Applications [0002] This application claims priority under 35 USC § 119(e) to Provisional Patent Application no. 61 / 584,666, filed January 9, 2012, the disclosure of which is incorporated herein by reference in its entirety. technical field [0003] The subject matter described herein relates to free-space optical (FSO) wireless communications, and more particularly, to enhanced optical transmission efficiency that can be achieved for beam propagation through optically compromised atmospheric conditions due to conditions Using the wavelength propagation of an ultrashort pulse laser (USPL) source, the conditions can include, but are not limited to, fog, atmospheric beam drift, scintillation effects, and the like. Background technique [0004] The explosive growth in demand for telecommunication services from the private as well as the commercial sector has put unprecedented pressure on currently available telecommunication networks. In th...
