Free-space optical transmission

We propose a novel secure free-space optical (FSO) communication scheme that seamlessly integrates ranging and phase encryption. Experimental demonstration over a 40-GBaud, 30-m FSO link is successfully validated, enabling flexible decoding distance-range and enhanced security.
