Photon transport through a nanohole by a moving atom

Abstract

We have proposed and investigated for the first time an efficient way of photon transport through a subwavelength hole by a moving atom. The transfer mechanism is based on the reduction of the wave packet of a single photon due to its absorption by an atom and, correspondingly, its localization in a volume is smaller than both the radiation wavelength and the nanohole size. The scheme realizes the transformation of a single-photon single-mode wave packet of the laser light into a single-photon multimode wave packet in free space.

Спектроскопия Квантовых Биений В Системе N Одинаковых, Близко Расположенных Атомов. I. Случай N=2

“…Были предложены различные подходы к ее решению -часть из них была реализована в эксперименте. Заслуживают быть отмеченными следующие идеи: 1) фотоэлектронная (фотоионная) микроскопия [1][2][3] в качестве дальнейшего развития идеи эмиссионного микроскопа Мюллера [4]; 2) резонансная передача молекулярного возбуждения от наноострия в макроскопический образец по механизму Фёрстера (fluorescence resonance energy transfer -FRET) [5]; 3) основанная на механизме FRET сканирующая микроскопия ближнего поля [6,7]; 4) сочетание оптического возбуждения с наноразрешением атомносилового или сканирующего туннельного микроскопа [8]; 5) перемещение атома, возбужденного лазерным излучением, через наноотверстие в металлическом экране [9]; 6) наноскопия пар квантовых точек, основанная на эффекте " мерцания" люминесценции и численном моделировании изображений [10].…”

Frequency stabilization of a diode laser on the 5P→ 5Dtransition of the Rb atom

“…But in a variety of experiments not only the ground and first excited atomic states are used but also higher-lying, primarily, D-states of atoms of alkali metals are involved (for example, in the case of rubidium, this is the → P D 5 5 transition). Thus, the second excited state of alkali atoms is used in experiments on studying Rydberg states [16] and building on quantum memory on their basis [17], single photon pair generation [18], in studies of the polarizability of atomic states [19] aiming at the construction of exact models of the intra-atomic dynamics [20], as well as in experiments on photon transport by single atoms [21].…”

“…3 2 5 2 transition of the rubidium atom. This transition makes it possible to excite rubidium atoms to the 5D state, and it is widely used in exper imental investigations in recent times [16][17][18]21]. The stabilization scheme of the laser considered in the paper is based on the absorption spectroscopy of the laser radiation in an atomic cell.…”

Spontaneous decay rate of an excited molecule placed near a circular aperture in a perfectly conducting screen: An analytical approach

“…Holes of different shapes in a metal film are widely used in optical and plasmonic nanodevices [1 -3]. It is a basic element of a near-field scanning optical microscope [4 -8], molecular sensors with nanoaperture [9 -17], the experiment on single photon transport by a moving atom [18,19], and a new type of a plasmon-atomic two-dimensional metamaterial [20]. Now, methods for precise positioning of a molecule inside a nanohole are being developed [21] opening new possibilities to control the radiation of a single quantum emitter.…”
