María 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.
Pascuala Garcia presented the communication entitled “On axis programmable microscope using liquid crystal spatial light modulator” at the SPIE Optical Metrology Conference, held in Munich in June 25th to 29th, 2007.
In her presentation, she showed an optical microscope system we have developed, that includes an LCOS SLM display to perform opto-digital filtering on-axis. We use a Hamamatsu SLM, free of flickering, which can be tuned to fully eliminate the zero order component of the encoded diffractive filter, therefore making use of the full space-bandwidth. The system was demonstrated by implementing different optical processing operations based on phase-only gratings such as phase-contrast, band-pass filtering, additive and subtractive imaging, or Differential Interference Contrast (DIC) imaging.

We were very pleased that Prof. Kristiaan Neyts, Head of the Liquid Crystals and Photonics Group from the Ghent University, accepted our invitation to come to Elche and impart a seminar on liquid crystals in the frame of the 3rd TECNIT PhD Workshop of our university, held in March 29th.
In this workshop he gave an invited talk entitled “Liquid-crystal spatial light modulator based optical ac¡architecture for the full polarization modulation – Application to encode optical polarization devices”.
The LCP workshop is always particularly friendly to attend, after our organization in 2010 in Elche.

On May 18th 2016, María del Mar Sánchez participated in the II Workshop on Women in Science & Engineering, held at the Politechnical School of Experimental Sciences & Technology, at University Rey Juan Carlos (URJC), Madrid.
Organized by Prof. Beatriz Romero, from URJC, this workshop is intended to encourage women to follow a career in science or engineering.
María del Mar participated with the conference entitled “Women researchers in Light and in Light Technologies – Investigadoras en la luz y en las tecnologías de la luz”.
Ignacio Moreno gave the invited talk entitled “Photonic Technologies: Essential told for current engineering”, at the XVII IEEE Spanish Student Branch Meeting, held in UMH – Elche. This meeting is organized by the IEEE Student Branchs in Spain, and this year it has been organized by the UMH IEEE Student Branch in April 7th to 10th.
During his presentation, Ignacio talked about all the possibilities that Optics & Photonics offer in the different areas of modern engineering, from fiber optics in communications, lasers of industrial applications, LEDs sources for lighting, or biomedical optical applications.

Ignacio Moreno presents an invited communication at the meeting SPIE Photonics Europe held in Brussels in April 2016.
The communication is entitled “Production of arbitrary polarized light beams with a liquid crystal spatial modulator”, and it was presented within the session Optical Micro- and Nanometrology. This communication reviews our recent advances in the design of polarization diffractive optical elements encoded onto a spatial light modulador system.
Our friend Prof. Juan Campos, from the Department of Physics at Universitat Autònoma de Barcelona (UAB) visited us on March 3rd and 4rth, 2016. Juan is the leader researcher in the national research projects we develop in collaboration.
Juan came to Elche to participate in the 3rd edition of the PhD Workshop of TECNIT – the Doctorate Program in Industrial & Telecommunications of UMH. He participated at the workshop by giving a talk entitled ADVANCES IN OPTICAL POLARIMETRY: DEVICES AND APPLICATIONS. This talk can be viewed at the above link.
Pascuala Garcia and Maria del Mar Sanchez met Jocelyn Bell at the Faculty of Physics of the University of Valencia.
Dr. Bell, renown astrophysicist famous for the discovery of pulsars, was invited to Valencia to give a conference within the cycle of seminars of the Faculty of Physics. Dr. Bell was one of the women selected for the Exhibition Women in Light Science and Light Technology. This exhibition coordinated by Pascuala García, and with the participation of María del Mar Sánchez, has been developed by members of the Group of Women in Physics of RSEF – Real Sociedad Española de Física, and from SEDOPTICA – Sociedad Española de Óptica.
The exhibition was inaugurated in September 2015 at the SEDOPTICA meeting XI Reunión Nacional de Óptica, held in Salamanca, and it has been exhibited at many different locations, including the University of Valencia, and the University Miguel Hernandez, where it can now be visited at the hall of the building Arenales, until April 11th, 2016.
María M. Sánchez-López and Ignacio Moreno attend the meeting SPIE Optics & Photonics held in San Diego during August 2015, 9th to 13th.
The oral communication entitled “Spectral characterization and tuning with liquid-crystal retarders” was presented within the session Optics and Photonics for Information Processing IX.
