Maximum time delay achievable on propagation through a slow-light medium

Robert W. Boyd, Daniel J. Gauthier, Alexander L. Gaeta +1 more

We consider the question of whether there are any fundamental limits to the maximum time delay that can be achieved for a pulse propagating through a slow-light medium. We include in our analysis what we consider to be the dominant competing effects, and we show that in principle they do not lead to a limitation on the maximum achievable time delay. From this result we conclude that, through optimization, one should be able to delay a pulse by very many pulse lengths; the ability to do so can have important implications for the use of slow-light methods for applications in photonics.We consider the question of whether there are any fundamental limits to the maximum time delay that can be achieved for a pulse propagating through a slow-light medium.

What are the limits to the time delay achievable using "slow-light" methods?

Robert W. Boyd, Nick N. Lepeshkin, Aaron Schweinsberg +6 more

Practical applications of slow light methods require that one be able to controllably delay a pulse of light by many pulse lengths. In this contribution we analyze the possible limitations to the maximum achievable time delay and suggest methods for overcoming these limits.

Distortion Management in Slow-Light Pulse Propagation

Ravi Pant, Michael D. Stenner, Mark Allen Neifeld

Slow light based devices require large delay compared to pulse width and small distortion. We describe methods for characterizing delay-induced pulse distortion and distortion management in slow-light systems.

Increase of the fractional delay of the pulse in an electromagnetically-induced-transparency medium

R. N. Shakhmuratov, J. Odeurs

We propose a nonadiabatic change of the control-field amplitude to restore the temporal shape of a signal pulse, which usually experiences an appreciable temporal broadening in a conventional regime of electromagnetically-induced-transparency. This broadening sets a major limit on the maximum time delay achievable in a slow-light medium. A circumvention of this limit may be useful for the application of a slow-light medium as a practical, controllable delay line.

Slow- and fast-light: fundamental limitations

Robert W. Boyd, Paul Narum

We present an analysis of the propagation of light pulses through materials possessing extreme values of the group velocity. We begin with an analysis of the behaviour that occurs upon propagation through materials possessing simple Lorentzian gain or absorption lines or materials possessing sharp dips in gain or absorption features. We also describe how more complicated lineshapes can be used to tailor the dispersion of a slow-light system. We furthermore present an analysis of fundamental limitations to how many pulse widths a pulse of light can be delayed or advanced. We show how these mechanisms lead to different limits for slow and fast propagation media.We present an analysis of the propagation of light pulses through materials possessing extreme values of the group velocity.
