Abstract

Nowadays, it is important to consider not only the possibility of information multiplexing, but also the security aspect of its transmission. This article presents a novel telecommunication system based on relative phase coding. A highly coherent source is used to transmit data, which consists of a sequence of time intervals of duration ?, each exhibiting a different phase. At the receiver, this sequence propagates through an imbalanced Mach-Zehnder Interferometer (MZI) exhibiting a differential time-delay matching the time-interval duration ?. At the MZI output, two consecutive intervals overlap, and interferences occur. If the phases of two consecutive intervals are identical, constructive interferences produce a binary '1' at the decoder output. Conversely, if the phases of these intervals differ by ?, destructive interferences produce a binary '0'.
