“…* gxhuang@phy.ecnu.edu.cn Before preceding, we note that DEIT has been explored in many previous studies, which showed that two probe fields can be made transparent by the use of control field [5][6][7][8][9][10]. Additionally, the storage and retrieval of the two probe fields in DEIT systems have also been demonstrated experimentally [11][12][13][14][15]. However, our work is different from Refs.…”

“…Furthermore, our work is also at variance with Refs. [11][12][13][14][15], where only the memory of two probe pulses in the linear propagation regime was explored. In contrast with these studies, in our work not only a nonlinear DEIT but also the storage and retrieval of two solitonic probe pulses in nonlinear propagation regime are explored.…”

We propose a scheme to realize storage and retrieval of two-component optical soliton in a coherent atomic system. The system under consideration is a cold, lifetime-broadened four-level atomic gas with a tripod configuration working at the condition of double electromagnetically induced transparency. We show that due to the existence of two dark states, the optical absorption of the probe pulse can be largely reduced. In addition, the two orthogonal polarization components of the probe pulse with a form of vector optical soliton cannot only be slowed down substantially but also be stored and retrieved robustly by switching a control laser field off and on. We also show that it is possible to achieve a memory of N -component optical soliton by using the N dark states in a (N + 1)-pod system (N > 2). The results reported here may have promise in applications for light information processing in a weak nonlinear regime.

“…Traditional two-mirror configurations of Fabry-P erot etalons can be difficult to stabilize or set up. [8][9][10][11] We present a filtering setup that relies on cascaded monolithic Fabry-P erot cavities to achieve fully customizable narrow linewidth transmission. Based on the idea of Palittapongarnpim et al, 12 this setup also permits simultaneous filtering of photons at orthogonal polarizations, and extends the free spectral range (FSR) to hundreds of GHz.…”

A monolithic polarization-independent frequency-filter system for filtering of photon pairs

We set up a long-term stable filtering system that consists of cascaded monolithic Fabry-Pérot filters to enhance the suppression and free spectral range. An effective free spectral range of hundreds of GHz allows the system to be used as a high resolution monochromator, with a linewidth of 192 MHz. As an important application a single mode is filtered from photon pairs generated by a parametric down-conversion source, and their indistinguishability is proven by measuring the Hong-Ou-Mandel effect with a visibility of 96%. We report that undesired birefringence, which is often encountered with monolithic cavities, can be avoided by stress-free mounting.

Abstract:Inspired by a recently experiment by M. Lettner et al. [Phys. Rev. Lett. 106, 210503 (2011)], we propose a robust scheme to prepare three-dimensional entanglement state between a single atom and a Bose-Einstein condensate (BEC) via stimulated Raman adiabatic passage (STIRAP) technique. The atomic spontaneous radiation, the cavity decay, and the fiber loss are efficiently suppressed by the engineering adiabatic passage. Our strictly numerical simulation shows our proposal is good enough to demonstrate the generation of three-dimensional entanglement with high fidelity and within the current experimental technology.
