Abstract

We show that the use of tunable photonic structures opens up unprecedented possibilities in information processing. In particular, we introduce an all-optical adiabatic bandwidth compression and frequency conversion process that overcomes the classical bandwidth-delay constraint in optics. This process requires only very small index modulations (δn/n<10^-4) performed at moderate speeds, and yet can alter the spectrum of a photon almost at will. As examples of this process, we show how light pulses can be stopped and stored all-optically in multitude of systems without using any resonant or coherent electronic interactions. We also show how light pulses can be time-reversed using only linear optical elements and modulators. Such systems open up new opportunities in both fundamental sciences and technological applications.
