Lattice Resonances Excited by Finite-Width Light Beams

Autor: Lauren Zundel, Juan R. Deop-Ruano, Rosario Martinez-Herrero, Alejandro Manjavacas

Publikováno v: ACS omega. 7(35)

Artículo con 6 figuras
Periodic arrays of metallic nanostructures support collective lattice resonances, which give rise to optical responses that are, at the same time, stronger and more spectrally narrow than those of the localized plasmons o

Partially Coherent Cylindrical Vector Sources

Autor: Massimo Santarsiero, Juan Carlos González de Sande, Olga Korotkova, Rosario Martínez-Herrero, Gemma Piquero, Franco Gori

Publikováno v: Photonics, Vol 10, Iss 7, p 831 (2023)

A new class of stationary electromagnetic sources radiating outward from the surface of an infinitely long cylinder is introduced via vectorial coherent mode representation. First, two particular types of such sources are discussed: with either an el

Experimental estimation of the longitudinal component of a highly focused electromagnetic field

Autor: David Maluenda, Marcos Aviñoá, Kavan Ahmadi, Rosario Martínez-Herrero, Artur Carnicer

Publikováno v: Scientific Reports, Vol 11, Iss 1, Pp 1-10 (2021)

Abstract The detection of the longitudinal component of a highly focused electromagnetic beam is not a simple task. Although in recent years several methods have been reported in the literature, this measure is still not routinely performed. This pap

Characterization of Partially Polarized Light Fields

Autor: Rosario Martínez-Herrero, Pedro M. Mejías, Gemma Piquero

Polarization involves the vectorial nature of light fields. In current applications of optical science, the electromagnetic description of light with its vector features has been shown to be essential: In practice, optical radiation also exhibits ran

Modal Analysis of Pseudo-Schell Model Sources

Autor: Massimo Santarsiero, Rosario Martínez-Herrero, Gemma Piquero, Juan Carlos González de Sande, Franco Gori

Publikováno v: Photonics, Vol 8, Iss 10, p 449 (2021)

All pseudo-Schell model sources have been shown to possess the same continuous set of circularly symmetric modes, all of them presenting a conical wavefront. For keeping energy at a finite level, the mode amplitude along the radial coordinate is modu

A New Type of Shape-Invariant Beams with Structured Coherence: Laguerre-Christoffel-Darboux Beams

Autor: Rosario Martínez-Herrero, Massimo Santarsiero, Gemma Piquero, Juan Carlos González de Sande

Publikováno v: Photonics, Vol 8, Iss 4, p 134 (2021)

A new class of sources presenting structured coherence properties is introduced and analyzed. They are obtained as the incoherent superposition of coherent Laguerre-Gaussian modes with suitable coefficients. This ensures that the shape of the intensi

Besinc Pseudo-Schell Model Sources with Circular Coherence

Autor: Rosario Martínez-Herrero, Gemma Piquero, Juan Carlos González de Sande, Massimo Santarsiero, Franco Gori

Publikováno v: Applied Sciences, Vol 9, Iss 13, p 2716 (2019)

Partially coherent sources with non-conventional coherence properties present unusual behaviors during propagation, which have potential application in fields like optical trapping and microscopy. Recently, partially coherent sources exhibiting circu
