Optical signal storage and switching between two wavelengths

Abstract

The authors report an experiment in which optical pulses are effectively stored via maximal atomic coherence in a three-level Λ-type Rb87 atomic system, and then selectively released at one of the two different wavelengths by turning on the retrieve control pulse at 794.9842 or 794.9698nm. The storage time up to 360ns was demonstrated.

Controlled release of stored optical pulses in an atomic ensemble into two separate photonic channels

Bo Wang, Shujing Li, Haibin Wu +3 more

We report an experiment in which optical pulses stored in an atomic system can be controllably released into two different photonic channels. By controllably turning on the retrieve control pulses at either 795 or $780\phantom{\rule{0.3em}{0ex}}\mathrm{nm}$ to read the stored optical pulses in a four-level double $\ensuremath{\Lambda}$-type atomic medium, we can obtain the released probe pulse at 795 or $780\phantom{\rule{0.3em}{0ex}}\mathrm{nm}$, respectively. These readout pulses can be further separated spatially and directed into different optical propagation channels through a grating. Such controlled release of stored optical pulses may extend the capabilities of the quantum information storage technique, and can have applications in multichannel all-optical switching, all-optical routing, quantum information processing, and image storage systems.

Optical pulse storage and forwarding with multi-wavelength conversion

W.C.R. Nascimento, D. P. Caetano, J. Miguel Hickmann

This study demonstrates a different type of all-optical switch with multi-wavelength conversion, capable of storing and controllably forwarding optical pulses. The mechanism behind this device is electromagnetically induced transparency, where an optical signal interacts resonantly with a three-level atomic system and a control field. To describe the dynamics of this system, a set of coupled partial differential equations is solved numerically.

Storage and retrieval of ultraslow optical solitons in coherent atomic system

Zhengyang Bai, Chao Hang, Guoxiang Huang

We investigate the propagation of intense probe pulses in a lifetime broadened Λ-type three-level atomic system with a configuration of electromagnetically induced transparency.We find that ultraslow optical solitons formed by a balance between dispersion and nonlinearity can be stored and retrieved in the system by switching off and on a control field.Such pulses are robust during storage and retrieval, and hence may have potential applications in optical and quantum information processing.

Resonance retrieval of stored coherence in an rf-optical double-resonance experiment

Vladimir Djokic, Georg Enzian, Frank Vewinger +1 more

We study the storage of coherences in atomic rubidium vapor with a three-level coupling scheme with two ground states and one electronically excited state driven by one optical (control) and one radio frequency field. We initially store an atomic ground state coherence in the system. When retrieving the atomic coherence with a subsequent optical pulse, a second (signal) optical beam is created whose difference frequency to the control field is found to be determined by the atomic ground state's Raman transition frequency.

Controlled light storage in a double lambda system

Andrzej Raczyński, Jarosław Zaremba, Instytut Fizyki Uniwersytet Miko̷laja Kopernika

The possibility is predicted that after light storing in a medium of four-level atoms it is possible to release a new pulse of a different frequency, the process being steered by another driving beam. It is also possible to store one pulse and to release two different ones, with their time separation and heights being controlled.

Storage and switching of multiple optical signals among three channels

Xiaoli Song, Aijun Li, Lei Wang +6 more

We experimentally and theoretically demonstrate that multioptical signals can be effectively stored and retrieved by fractional stimulated Raman adiabatic passage technique in a tripod-type four-level $^{87}\text{R}\text{b}$ atomic system. The optical pulses stored can be controllably released into two of the three different channels. The restored pulses have the same frequency, polarization, and propagation direction as the writing pulses. The experimental results fit very well with the numerical simulations.
