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

Abstract

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.

Tunable Light-Storage for almost 1 Microsecond

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.

A Review to the All-Optical Quasi-Light Storage

In this paper, we compare two methods to delay optical signals based on quasi-light storage (QLS). These methods are very simple and offer high-tunable storage times up to several thousand bits. Furthermore, they are transparent to the bit rate and modulation format of the signal. We explore the potentials and limitations of both methods. Fiber-based QLS is useful when high absolute delay is required and no loss or very small amount of attenuation can be tolerated. Frequency-to-time-conversion-based QLS can be used for the delay of very high bandwidth signals.

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.

We propose the tunable storage of 8Bit data packets for up to 500ns by extension of the Quasi-Light-Storage method. Easy tuning of the storage time in the whole range is possible using conventional telecommunication components.
