USPL-FSO LASERCOM POINT-TO-POINT AND POINT-TO-MULTIPOINT OPTICAL WIRELESS COMMUNICATION
First Claim
1. An optical communication apparatus comprising:
- an ultra-short-pulse-laser (USPL) source that generates a beam comprising light pulses each having a duration of approximately 1 of nanosecond or shorter;
a modulation element that applies a modulation signal to the beam generated by the USPL source to generate a modulated optical signal, the modulation signal carrying data for transmission to a second optical communication apparatus;
an optical transceiver that receives the modulated optical signal and transmits the modulated optical signal for receipt by the second optical communication apparatus.

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.
