Light sources based on optical fibers with special modes (2014-2016)

(Ref.: TEC2013-46643-C2-1-R, funded by the Ministerio de Economía y Competitividad of Spain and the European Regional Development Fund)

Logos

The central idea of the project is the use of the modal spectrum of the optical fibers in order to take profit of the particular properties of specific high-order modes. This subject lies within the context of developing high capability optical communications by exploiting space division multiplexing techniques, few mode fibers and multi-core fibers. The design of an optical fiber permits to obtain modes whose properties (dispersion, modal area, intensity distribution) are very different from the ones of the fundamental mode. Individual excitation and propagation of these modes make feasible the use of these properties in different applications related but not restricted to communications, such as lasers, amplifiers, special light sources (supercontinuum, photon pairs, frequency combs, etc.), sensors and optical switches

International Collaboration on Integrated Photonics Technologies for Advanced Bioapplications (iPhoto-Bio, 2014-2018)

(Ref.: PIRSES-GA-2013-612267, http://cordis.europa.eu/projects/rcn/109755_en.html)

The objective of the proposed joint exchange programme "iPhoto-Bio" is to establish long-term stable research cooperation between the partners with complimentary expertise and knowledge. The project objectives and challenges present a balanced mix between industrial application focused knowledge transfer and development and more far-looking studies for potentially ground-breaking applications by exploiting new emerging opportunities with the integration of photonic components and systems (photonic crystal fibres, fibre tapers and tips, fibre gratings, micro-nano-bio systems), new functional techniques and innovative materials (nanoparticles, biocompatible materials, laser micromachining, surface Plasmon technology, Terahertz detection technique) for advanced applications in the health and biomedical (i.e. label-free biosensing, realtime monitoring, early diagnosis of disease), food sectors (quality and safety) and environment. No an individual group in EU can accomplish the proposed work alone, the proposal collaborations with non-EU project partners are therefore vital to gain their skills and expertise in the above-mentioned areas.

Photonic crystal fiber supercontinuum and laser sources (2009-2013)

(Ref.: TEC2008-05490)

The aim of this project is to obtain new all-fiber light sources based on the photonic crystal fiber (PCF) technology. We will focus on fiber lasers operating on continuous wave, Q-switched or mode-locked regime, and their combination with highly non-linear PCF for supercontinuum generation in all-fiber systems.

The project includes the fabrication of rare-earth-doped PCF, nonlinear PCF and other special fibers as dual-core, photosensitive and polarizing PCF. We will take advantage of different postprocessing techniques, as tapering and Bragg gratings photo-inscription, to realize the PCF components that the project requires. Acousto-optic in-fiber interaction and nonlinear coupling in dual-core PCF will be exploited as all-fiber modulators. The tapering of PCF will permit a precise engineering of the group velocity dispersion, the enhancement of the acousto-optic interaction, a fine control of the coupling in dual-core PCF and the mode adaptation between dissimilar fibers.

In addition to analyze real PCF, taking into account the details of the geometry by means of an electronic microscope image, we will develop automatic designing tools to obtain PCF with specific properties. We will address the vector propagation of optical pulses in PCF and PCF tapers by solving properly the generalized nonlinear Schrödinger equation, in order to study the polarization dynamics of supercontinuum generation and the design of taper transitions to attain adiabatic soliton compression to the few-optical-cycle regime. Finally, we will tackle the task of describing the evolution of the mutual coherence function of short pulsed light in nonlinear regime after propagation inside PCF.
