We report experimental observations of a large Bragg reflection from arrays cold atoms trapped near one-dimensional nanoscale waveguide. By using an optical lattice in the evanescent field surrounding nanofiber with period nearly commensurate resonant wavelength, we observe reflectance up to 75% for guided mode. Each atom behaves as partially reflecting mirror and ordered chain about 2000 is sufficient realize efficient mirror. Measurements spectra function probe polarization are reported....
An adaptive synchronous machine controller that minimizes a cost function incorporating system input, output, and set-point variations, its application to multimachine power are described. The control is based on criterion of automatically shifting the closed loop poles towards origin in z-domain without violating constraints. It possesses property robustness ease reference signal tracking. ability proposed damp multimode oscillations investigated. Studies show cooperates with conventional...
Quantum photonic devices operating in the single photon regime require detection and characterization of quantum states light. Chip-scale, waveguide-based are a key enabling technology for increasing scale complexity such systems. Collecting photons from multiple outputs at end-face chip is core task that frequently non-trivial, especially when output ports densely spaced. We demonstrate novel, inexpensive method to efficiently image route individual modes polymer chip, where undergo walk....
The Rydberg atomic quantum receiver (RAQR) is an emerging precision sensing platform designed for receiving radio frequency (RF) signals. It relies on creation of atoms from normal by exciting one or more electrons to a very high energy level, which in turn makes the atom sensitive RF RAQR realizes RF-to-optical conversion based light-atom interaction relying so called electromagnetically induced transparency (EIT) and Aulter-Townes splitting (ATS), that desired signal can be read out...

Summary form only given. Reversible light-matter interfaces are crucial elements in quantum optics and information networks. In particular, the coupling of one-dimensional bosonic nanoscale waveguides cold atoms appears as a promising pathway to build strong interaction thanks tight transverse confinement light.Recently, our group has developed an interface where light, tightly guided by subwavelength-diameter optical fiber (nanofiber), strongly interacts with near its vicinity. this case,...
By trapping cold atoms in the evanescent field of an optical nanofiber, we store and reflect guided pulses at single-photon level. We also herald, read out a single waveguide-coupled collective atomic excitation.
Summary form only given. Developing light-matter interfaces is a crucial capability with unique applications to quantum optics and information networks [1]. In this context, our group focuses on the study of interactions between photons guided by nanoscale waveguides arrays trapped atoms. Nanoscale offer compelling platform because tight transverse confinement propagating light, strong photon-atom coupling in single pass, potential long-range atom-atom interaction mediated [2]. Our platform,...
