“…On the one hand, bright ORPs have been proposed and demonstrated with high-azimuthal-order Laguerre-Gaussian (LG) beams [199] and also with annular microlenses [200,201]. Azimuthal lattices within ORPs have been demonstrated with time orbiting of light beams [202,203] and by interference of LG beams of different azimuthal orders [204]. A one-dimensional stack of ORPs in a line has been proposed in an optical cavity [205] and demonstrated with axicon beams [206].…”

A mis padres, hermanos, sobrinos y a Raquel AcknowledgmentsTot té un principi i un final i aquest serà el punt final a una etapa de la meva vida la qual estic segur que d'aquí uns anys, quan miri enrere, veuré que ha estat probablement la que ha tingut una major rellevància tant a nivell personal com científic. Quan vaig acabar la carrera no tenia gaire clar quin camí seguir però vaig tenir la sort de parlar amb qui ha estat el meu director de tesi, el Jordi, qui em va guiar i va posar tota la seva confiança en mi des del primer moment. Em va oferir un tema original i es va aventurar a dirigir una tesi amb una forta vessant experimental, tot un atreviment venint d'un teòric! Quan vaig començar el Màster, si m'haguessin dit on he arribat 5 anys després mai m'ho hauria cregut i, Jordi, tu tens gran part de culpa de tot això. Moltes gràcies per haver confiat en mi des del primer dia, per haver-te mostrat sempre tan orgullós de tot el que he fet, per haver estat sempre disponible i per ajudar-me i animar-me quan he passat moments durs durant aquest anys. M'has ensenyat a ser un bon científic, a moure'm dins aquest món, a creure em mi i a ser una millor persona. Mai t'estaré prou agraït per tot això i per haver sigut tan proper amb els teus cotilleos, converses de futbol, política, noies, etc. dinant al bar. Has estat com un pare per a mi (bueno, un germà gran, que tampoc ets tan vell per a ser Mompare :P). Si el Jordi ha estat el meu pare en la ciència, el Yury ha estat el meu gurú científic. Mai he trobat una persona tan pacient, que sàpiga tant de qualsevol tema i amb tanta dedicació com tu. M'has ensenyat a ser riguròs, a tenir un mètode, la importància de estar al dia de tot el que es fa en el cap d'estudi, a programar, i un llarg etcètera. En resum, m'has ajudat a donar-me forma a mi mateix com a científic i a tenir perseverança en el que faig. Tot això sense oblidar que per a mi ets un gran amic! Seguidament, també he donar les gràcies al Todor, una de les persones més enèrgiques que conec i amb més passió per la ciència. Tu vas iniciar tot el tema de la refracció cònica al nostre grup i has demostrat que ets realment qui més coneix de cristalls i del fenomen en si. Si no hagués estat per tu, no podríem haver començat res d'això i no podríem haver explotat el fenomen ni una quarta part del que hem fet. Ets un exemple per tenir sempre un somriure a la cara i per aquesta iii iv força que et fa tirar endavant tots els teus projectes. També vull donar les gràcies a altres companys del Grup d'Òptica, començant per la Verònica, que va passar de ser una "professora de la carrera" a ser el meu ideal de constància i l'esforç. Ets un exemple professional a més a més d'una persona molt més propera i alegra del que pot semblar a primera vista. A Ramón también le tengo que agradecer su ayuda y su disponibilidad a lo largo de estos años, su paciencia cuando ha tenido que soportar mis imitaciones y su alegría y naturalidad en todo momento. Amb el Francesc també he compartit molts bons moments, sobretot a les diverses activit...

“…Among the DOEs that generate optical vortices are phase spiral plates [2,3], helical axicons [4,5,6] and spiral zone plates [7]. The ability of the fork-shaped holograms and diffraction gratings to produce vortex beams from an incident Gaussian laser beam was experimentally verified [8,9] and after, widely used for guiding cold atoms [10,11], optical manipulation of micron-sized objects [12,13], and in quantum information applications [14,15], since these vortex beams carry definite photon orbital angular momentum [16].…”

Abstract:In this article we present a theoretical study for Fraunhofer diffraction of a LaguerreGaussian laser beam with zeroth radial mode number and azimuthal mode number l by diffractive grating with embedded fork-shaped dislocations of integer order p. Analytical expressions describing the diffracted wavefield amplitude and intensity distributions in the Fourier plane are deduced and analyzed. They are also followed by the vortex radii expressions.

We have demonstrated preparing and rotating single neutral rubidium atoms in an optical ring lattice generated by a spatial light modulator, inserting two atoms into a single microscopic optical potential efficiently by dynamically reshaping the optical dipole trap, trapping single atoms in a blue detuned optical bottle beam trap, and confining single atoms into the Lamb-Dicke regime by combining red and blue detuned optical potentials. In combination with the manipulation of internal states of single atoms, the study is opening a way for research in the field of quantum information processing and quantum simulation. In this paper we review the past works and discuss the prospects. laser cooling and trapping, single atoms, quantum information processing, quantum simulation Citation:Yu S, He X D, Xu P, et al. Single atoms in the ring lattice for quantum information processing and quantum simulation. Chin Sci Bull, 2012Bull, , 57: 1931 1945Bull, , doi: 10.1007 Single neutral atoms are promising candidates for quantum information processing [6,7]. A qubit can be encoded in the internal or motional states of an atom, and multi-qubit operations can be performed based on atom-light interactions or atom-atom interactions. In particular, the hyperfine ground states of alkali-metal atoms can be considered as qubits, which can be easily manipulated via microwave radiation or Raman transitions. Several kinds of proposals for quantum gate operation were designed based on dipoledipole interactions between Rydberg atoms [8], cavity-mediated photon exchange [9] and controlled collisions [10]. Furthermore, single atom array can serve as a research platform for physical models described in other systems that are not directly investigated experimentally. The few-body simulation offers an opportunity to understand some intriguing many-body phenomena, such as superconductivity in solid materials [11], and the natural process of photosynthesis [12]. Instead of being adiabatically transferred from ultracold atomic ensemble, in our experiment single atom array is built one by one based on "collisional blockade" mechanism [13,14] that locks the atom number either zero or one in ultra small dipole trap in the presence of near-resonant laser light. Here, we demonstrate trapping single neutral rubidium atoms in the ring lattice generated by a computer controlled spatial light modulator (SLM), and present several kinds of manipulations of single atom array.
