Photonic Imaging Networks

Abstract

We have selected as a prototype application diagnostic medical imaging and visualization. We have developed several radiological visualization station we have developed and evaluated methods for the loss less compression of images and image-formate data over a lossy packet network. We have studied noise mechanisms in transparent photonic networks. We have demonstrated parallel-to-serial and serial-to-parallel conversion using spectral domain four-wave mixing with 150 fsec laser pulses reaching serial data rates of over 1 Tbit/sec. we have constructed and demonstrated a nonlinear optical processor based on three-wave mixing in nonlinear LBO crystals. We have employed the parallel-to-serial and serial-to-parallel processors for experimental demonstration of transmission of image information through an optical fiber channel. We have analyzed the secrecy capacity of a quantum cryptographic protocol for secret key generation and found that it primarily depends on estimates of information in eavesdropper's possession, and the expected fraction of inconclusive outcomes. We investigated experimentally a novel frequency division long distance interferometer for implementing quantum cryptographic protocol and found that signals are not affected by transmission over optical fiber, we have developed for the first time the rigorous definitions and the mathematical formalism for information leakage through possible eavesdropping on the quantum channel. We quantify effective defense frontiers against eavesdroppers attacks.
