Secure communications by optical homodyne
Willard H. Wells, Russel Stone, E. Miles · IEEE Journal on Selected Areas in Communications · 1993
It is shown that optical homodyne techniques offer a family of schemes for secure communications. Following some background in secure optical communications, a particular scheme is described and compared to cryptography. The scrambler built is also described, and security is discussed. Experimental results for point-to-point links in single-mode polarization-maintaining fibers are presented. Various enhancements and network compatibility are analyzed.>
