Tunable Light-Storage for almost 1 Microsecond

Abstract

We describe the latest results of the investigation of a new method to store optical packets called Quasi-Light-Storage (QLS). We discuss the method and show experimental results with a delay-bandwidth product of around 700 Bit.

Quasi-Light Storage: A Method for the Tunable Storage of Optical Packets With a Potential Delay-Bandwidth Product of Several Thousand Bits

Thomas Schneider, Kambiz Jamshidi, Stefan Preußler

We investigate and discuss the possibilities and limits of a method for the tunable storage of optical packets called Quasi-Light Storage (QLS). The QLS is simply based on a sampling in the frequency domain. Hence, it is independent of the data rate, the modulation and the wavelength of the optical packets. It works at room temperatures in standard fibers with off-the-shelf telecom equipment. As we will show in theory, the method has the potential to store packets with several thousand Bits of data from Zero to up to 100 ns. In the experiments we have stored several 8 Bit packets with a data rate of 1 Gbps for up to 100 ns, which corresponds to a delay-bandwidth product of 100 Bit.

A proposal for a tunable light storage method based on Quasi-Light-Storage and frequency-to-time-conversion

Kambiz Jamshidi, Christian‐Alexander Bunge, Thomas Schneider

We propose a quasi-light-storage method which is based on frequency-to-time conversion and capable of being integrated with a delay-bitrate product of 50 bits. The delay can be tuned in fine and coarse range easily.

All-optical coherent stopping and storage of light

Shanhui Fan, Mehmet Fatih Yanik

We show that light can be stopped and stored coherently with an all-optical adiabatic bandwidth compression process, without any coherent or resonant light-matter interactions. Such a process overcomes the fundamental bandwidth-delay constraint in optics.

Optical Packet Delay Using Channelized Slow Light

Zhimin Shi, Robert W. Boyd

We propose a new scheme of channelized slow light without the need of dynamic phase control among all spectral channels. Such a device with practical designs can achieve discretely-tunable packet delays with very small data-distortion.

Large group delays and long storage times for optical pulses in atomic vapor cells

Irina V. Novikova, D. F. Phillips, Ronald Lee Walsworth

We achieve large fractional delays in slow and stored light in atomic vapors using temporally shaped control fields. Combined with amplification, temporal control allows for pulse transmission with pulse bandwidth preservation and minimal distortion.
