Stopping Light All Optically

Abstract

We show that light pulses can be stopped and stored coherently, with an all-optical adiabatic and reversible pulse bandwidth compression process. Such a process overcomes the fundamental bandwidth-delay constraint in optics and can generate arbitrarily small group velocities for any light pulse with a given bandwidth, without any coherent or resonant light-matter interactions. We exhibit this process in optical resonators, where the bandwidth compression is accomplished only by small refractive-index modulations performed at moderate speeds.

All-optical stopping and quantum coherent storage of light

Mehmet Fatih Yanik, Shanhui Fan

We show that light pulses can be stopped and stored all-optically, with a process that involves an adiabatic and reversible pulse bandwidth compression occurring entirely in the optical domain. Such a process overcomes the fundamental bandwidth-delay constraint in optics, and can generate arbitrarily small group velocities for any light pulse with a given bandwidth, without the use of any coherent or resonant light-matter interactions. We exhibit this process in optical resonator systems, where the pulse bandwidth compression is accomplished only by small refractive index modulations performed at moderate speeds. The optically achievable ultra low speeds can also generate extremely large non-linearities using non-resonant interactions, and thus enable decoherence-free single photon quantum gates.

All-optical coherent stopping, storage, and time-reversal of light

Mehmet Fatih Yanik, Shanhui Fan

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.

Stopping and storing light coherently

Mehmet Fatih Yanik, Shanhui Fan

We present a general analysis for the criteria to stop and store light coherently. We show that a light pulse can be stopped in any physical system, provided that (i) the system bandwidth can be compressed to zero; (ii) the system has sufficient degrees of freedom to accommodate the pulse, and the bandwidth compression occurs while the pulse is in the system; and (iii) the bandwidth compression is done reversibly in an adiabatic fashion that preserves the phase space and the information in the original photon pulse during the entire duration of the stopping process. Based upon this general criterion, we present a brief discussion of stopping-light schemes using atomic resonances, and a detailed analysis of the all-optical scheme that we recently proposed. We show that the all-optical scheme can achieve arbitrarily small group velocities for large bandwidth pulses, and opens up new opportunities in both fundamental sciences and technological applications.

Generalized fast, slow, stop, and store light optically within a nanoring resonator

Nithiroth Pornsuwancharoen, Preecha P. Yupapin

Abstract We propose a remarkably simple system of an all optical system that can be used to fast, slow, stop, and store light coherently. The proposed system consist two micro and a nanoring resonators that can be integrated into a single system, which can be used to overcome the problem of bandwidth delay constraints with small group velocities. The large bandwidth is generated by a soliton pulse within a Kerr type nonlinear medium where an all optical adiabatic and reversible pulse bandwidth compression can be performed. The balance between dispersion and nonlinear lengths of the soliton pulse exhibits the soliton behavior known as self‐phase modulation, which introduces the optical output (i.e., gain) constant, which means that light pulse can be trapped, that is, stopped coherently within the nanowaveguide. The time independent optical gain is stored within the nanoring device, which is available for read only memory use. The memory time of 1 ps is achieved. © 2009 Wiley Periodicals, Inc.

Proposed Nonlinear Microring Resonator Arrangement for Stopping and Storing Light

A simple system of an all-optical system for stopping and storing is proposed. A system consists of two microring and a nanoring resonators that can be integrated into a single system. The large bandwidth is generated by a soliton pulse within a Kerr-type nonlinear medium where an all-optical adiabatic and pulse bandwidth compression can be performed. The balance between the dispersion and nonlinear lengths of the soliton pulse exhibits the soliton behavior known as self-phase modulation, which produces a constant optical output. This means that light pulse can be trapped, i.e., stopped optically within the nano waveguide.
