ICFO - The Institute of Photonic Sciences
ICFO is a young research institution that aims to advance the very limits of knowledge in Photonics, namely the science and technology of harnessing Light. Light, especially laser light, is one of the major enabling technologies currently available to humankind. Our research thrusts target the global forefront of photonics, and aim to tackle important challenges faced by society at large. We focus on current and future problems in Health, Energy, Information, Safety, Security and caring for the Environment.

Unravelling the Metabolic Progression of Breast Cancer Cells to Bone Metastasis by Coupling Raman Spectroscopy and a Novel Use of Mcr-Als Algorithm
(ACS, 2018-03-28)
Accés restringit per política de l'editorialRaman spectroscopy (RS) has shown promise as a tool to reveal biochemical changes that occur in cancer processes at the cellular level. However, when analyzing clinical samples, RS requires improvements to be able to resolve ... -
Imaging Nanometer Phase Coexistence at Defects During the Insulator−Metal Phase Transformation in VO2 Thin Films by Resonant Soft X‑ray Holography
(ACS, 2018-05-16)
Article
Accés obertWe use resonant soft X-ray holography to image the insulator−metal phase transition in vanadium dioxide with element and polarization specificity and nanometer spatial resolution. We observe that nanoscale inhomogeneity ... -
Singly-Resonant Optical Parametric Oscillator Based on Orientation-Patterned Gallium Phosphide
(OSA, 2018-03-26)
Comunicació de congrés
Accés obertWe report a pulsed singly-resonant optical parametric oscillator based on orientation-patterned gallium phosphide pumped by a Q-switched Nd:YAG laser. The mid-IR idler can be tuned across 2.8-3.1 μm with an average power of 20 mW. -
Multimilliwatt, tunable, continuous‐wave, mid‐infrared generation across 4.6‐4.7 m based on orientation‐patterned gallium phosphide
(OSA, 2018-05-06)
Article
Accés obertWe report the generation of tunable continuous-wave (cw) mid-infrared (mid-IR) radiation across 4608–4694 nm using the new nonlinear material, orientation-patterned gallium phosphide (OP-GaP). By exploiting difference-frequency ... -
Energy-dependent path of dissipation in nanomechanical resonators
(Nature, 2017-05-15)
Article
Accés obertEnergy decay plays a central role in a wide range of phenomena1,2,3, such as optical emission, nuclear fission, and dissipation in quantum systems. Energy decay is usually described as a system leaking energy irreversibly ... -
Enhanced graphene nonlinear response through geometrical plasmon focusing
(AIP, 2018-01-01)
Article
Accés restringit per política de l'editorialWe propose a simple approach to couple light into graphene plasmons and focus these excitations at focal spots of a size determined by the plasmon wavelength, thus producing high optical field enhancement that boosts the ... -
Transient nonlinear plasmonics in nanostructured graphene
(OSA, 2018-04-06)
Article
Accés obertPlasmons in highly doped graphene offer the means to dramatically enhance light absorption in the atomically thin material. Ultimately the absorbed light energy induces an increase in electron temperature, accompanied by ... -
Structural Coloring of Glass Using Dewetted Nanoparticles and Ultrathin Films of Metals
(ACS, 2016-04-22)
Article
Accés obertMetal nanoparticles have been used for coloring glass since antiquity. Colors are produced by light scattering and absorption associated with plasmon resonances of the particles. Recently, dewetting at high temperature has ... -
