XXXVII Bienal de Fisica, Zaragoza, July 2019

BienalPascuala García, María del Mar Sánchez, and David Marco attended the Bienal de Física, the biannual Spanish meeting of Physics, organized in Zaragoza by the Spanish Royal Physics Society(RSEF) (link)

David presented the poster entitled «Parallel generation of vortex beams with a 2D optical triplicator geometric phase design» in the Symposium of Quantum Optics (see here the related publication). And Pascuala presented the flash talk entitled «Highly efficient generation of arbitrary vector beams» in the Symposium of Applied Photonics (see here the related publication).

Pascuala also organized and chaired the session of Women in Physics, where María del Mar gave a talk on the activity promoting women in STEM entitled «Jornadas La Ciencia tiene nombre de Mujer de la Universidad Miguel Hernández».

 


 

IONS 2019, Barcelona, June 2019

David Marco and Julio César Quiceno participated at IONS 2019, Barcelona, June 2019. They have enjoyed the interesting conferences, scientific discussions and networking opportunities of this conference hosted by the OSA student chapter at ICFO and backed by the International OSA Network of Students. Link to the conference.

In his talk entitled «Two-dimensional geometric phase vortex grating based on the optimal triplicator design», David presented the design and characterization of a liquid-crystal geometric phase diffraction grating that generates 3×3 diffraction orders with vortex beams of different topological charges, and showed the operation of this grating as a vortex detector. These results have recently been published in Optics Express: link to the paper.

Julio César presented a poster entitled “Hybrid vector beams generated by cascaded q-plates” where he demonstrated a q-plate-based optical system capable of generating a variety of hybrid vector beams, and showed the rotation of their polarization pattern when comparing the near field and the far field captures. This optical system is more compact than those based on SLMs whilst bearing a notable degree of versatility.

2017

 

RSEFMaría del Mar Sanchez gave a talk about the generation of vectors beams with q-plate devices at the Meeting of the Royal Spanish Physical Society held in Santiago de Compostela in July 2017, 17th-21st, within the Symposium of Quantum & Non-linear Optics.

In this presentation, Maria del Mar reviewed some of our recent works. In the first part of the talk she presented the  performance of q-plates, and their combination to build other effective q-plates. In the second part she described the  implementation of q-plates on spatial light modulators, as well as their combination with axicon elements to create vector Bessel beams where both the topological charge and the polarization state vary upon propagation.
