Abstract

This thesis presents the experimental study and design of a coherent communication system by using phase shift keying (PSK). Systems are designed by using all passive elements, which make the system very easy to operate, and less maintenance is required. All the PSK designs are based on a single light source. In this thesis there are five different types of PSK with a single light source communication systems are designed. All designs are experimentally tested in free space. The systems are • All optical two-channel PSK communication system, by using single light source, "All optical single channel, two-way PSK communication, by using a single light source, "Two-way single channel PSK communication, using a lime delay unit", "Two-way single channel PSK communication without a delay unit", "All optical two-channel, two-way PSK communication, by using a single light source and Coherent length dependent multi­ channel PSK communication system using a single light source". Interaction of different channels in the same system is also studied. Solutions are proposed for the presence of interference in the multi­channel system. The main thrust of the work relies on dividing and redirecting the light wave from a single light source for PSK coherent communication.
