Topology Transitions of Anisotropy Induced Bound States in the Continuum
(2018)
Text en actes de congrés
Accés obertWe demonstrate that Bound states In the Continuum (BICs) are supported in planar anisotropic structures where the optic axes are arbitrarily oriented. Moreover, we reveal fundamental new topological properties of these ... -
Existence loci of bound states in the continuum in the parameter space of anisotropic planar structures
(Optical Society of American (OSA), 2019)
Comunicació de congrés
Accés obertBound states in the continuum (BICs), first predicted in the field of quantum physics [1], are localized radiationless states existing in the part of the spectrum that corresponds to radiative modes. BICs are a general ... -
Waveguide stopped light mediated by mode transitions
(Optical Society of American (OSA), 2019)
Comunicació de congrés
Accés obertHyperbolic metamaterials (HMMs) are uniaxial materials that have hyperbolic dispersion curves. There are two types of hyperbolic metamaterials, type I that is described by a permittivity tensor with e|| < 0 and e¿ > 0, and ... -
Complex light-assisted optical metrology techniques
(International Society for Photo-Optical Instrumentation Engineers (SPIE), 2018)
Text en actes de congrés
Accés restringit per política de l'editorialThe on-demand tailoring of the properties of light, such as phase, polarization or spatial shape, has completely changed the landscape of photonic-based applications. In this way, complex light fields have become an ... -
Bound states in the continuum in anisotropic structures
(Institute of Electrical and Electronics Engineers (IEEE), 2017)
Text en actes de congrés
Accés restringit per política de l'editorialWe report theoretical and experimental observation of radiationless bound states in the continuum (BIC) in waveguiding anisotropic structures. BICs may have all possible polarizations and be the only possible boundstates ... -
Conmutacion totalmente optica de ondas guiadas en medios virefring.
(1993)
Text en actes de congrés
Accés obertA new kind of tunable all-optical guided-wave thresholding device using waveguides consisting of both birefringent linear media and isotropic nonlinear media is discussed. The behavior of the lower threshold with a suitable ... -
Ondas híbridas en guías ópticas ultradelgadas
(1993)
Text en actes de congrés
Accés obertThe existence conditions and waveguiding properties of new hybri.d, TE and TM dominant waves guided by ultrathin organic films cladded by birefringent crystals are reported -
Sensores opticos integrados: una revision del estado actual del arte
(Universitat Politècnica de València, 1993)
Text en actes de congrés
Accés obertThe state of the art on integrated optical sensor technology is briefiy reviewed. Applications, problems to overcome, and potential in the future are introduced. -
Engineering of effective quadratic and cubic nonlinearities in two-period QPM gratings
(OPTICAL SOCIETY OF AMERICA, 2000)
Text en actes de congrés
Accés obertSummary form only given. Quasi-phase-matching (QPM) by electric-field poling in ferro-electric materials, such as LiNbO/sub 3/, is promising due to the possibilities of engineering the photolithographic mask, and thus the ... -
Vortex nucleation and evolution in parametric wave mixing
(Institute of Electrical and Electronics Engineers (IEEE), 1999)
Text en actes de congrés
Accés obertWe predict a variety of new phenomena, that includes the spontaneous nucleation of multiple vortex twins, vortex rotation and drift, vortex-antivortex interaction and annihilation, and formation of quasi-aligned patterns ... -
Trapping of light beams and formation of spatial solitary waves in quadratic nonlinear media
(Institute of Electrical and Electronics Engineers (IEEE), 1996)
Text en actes de congrés
Accés obertSummary form only given. In this paper we report the outcome of our comprehensive investigations to study the dynamics of the beam trapping in both bulk crystals and optical planar waveguides made of quadratic nonlinear ... -
A measure of flow vorticity with twisted beams of light
(Curran, 2016)
Text en actes de congrés
Accés restringit per política de l'editorialThe measurement of vorticity, a parameter providing local measurements of rotation at every point in a flow, would greatly assist research fields as diverse as biology microfluidics, complex motions in the oceanic and ...
