Not Accessible

Your library or personal account may give you access

Abstract

We demonstrate 4-Gbit/s underwater transmission of multiplexed four green OAM beams using directly-modulated 520-nm laser diode. The influence of various channel conditions, including scattering, water currents and temperature gradient (water turbulence) on system performance is investigated.
