Abstract : Our research focussed on experimental realization and information theoretic analysis of quantum cryptosystems. We have introduced and, using the acquired equipment, conducted preliminary experiments on transmission of photon phase information, employing frequency division technique suitable for practical realizations over frere space or optical fiber network. The 2-3 order of magnitude mismatch between fiber and electronic device capacity can be used to increase the speed, reduce latency, increase security and reliability in the transmission and distribution of image information. To implement these applications, we used the equipment to construct an all optical pre-processor at the transmitter and a post-processor at the receiver which performs multiplexing and demultiplexing, respectively. We have been investigating the diffractive optics with multifunctionality in polarization as well as programmable diffractive optics during the last five years employing natural birefringent and electrooptic nonlinear materials. Recently we initiated research into artificial dielectric materials (nanostructures) for photonic device applications. The acquired equipment also contributed to our characterization effort in the area of artificial dielectrics and diffractive optics.
