Martínez Herrero, Rosario ; Maluenda, David ; Juvells, Ignasi ; Carnicer, Artur | IEEE Computer Society | 2019-02-18According to intensity consideration along the propagation axis, we derived mathematical conditions for a family of modulating functions able to produce needles of arbitrary length, sub-wavelength width and almost constant irradiance. These func[...]texto impreso
Maluenda, David ; Juvells, Ignasi ; Martínez Herrero, Rosario ; Carnicer, Artur | Optical Society American | 2019-05-15Optical needles produced by means of diffractive technology might display limited quality and uniformity. It has been suggested that the bulky optical elements present on these setups can be responsible of such behavior. In particular, issues su[...]texto impreso
Maluenda, David ; Carnicer, Artur ; Jubells, Ignasi ; Martínez Herrero, Rosario | Spie-Int Soc Optical Engineering | 2017In this communication we analyze the light field distribution of a highly focused radially polarized beam when passes through a linear polarizer. The polarizer is modeled as a plane-parallel uniaxial absorbing medium with the optical axis parall[...]texto impreso
Martínez Herrero, Rosario ; Jubells, Ignasi ; Maluenda, David ; Carnicer, Artur | Spie-Int Soc Optical Engineering | 2019In the present communication, we describe how to produce long light distributions in the focal area of a high numerical aperture optical system using a custom modulation function with spiral charge. This analysis expands our previous development[...]texto impreso
Martínez Herrero, Rosario ; Maluenda, David ; Juvells, Ignasi ; Carnicer, Artur | Nature Publishing Group | 2017-02-13Polarisers are one of the most widely used devices in optical set-ups. They are commonly used with paraxial beams that propagate in the normal direction of the polariser plane. Nevertheless, the conventional projection character of these devices[...]texto impreso
Martínez Herrero, Rosario ; Maluenda, David ; Carnicer, Artur | Nature Publishing Group | 2018-02-08We introduce a new method for producing optical needles with tunable length and almost constant irradiance based on the evaluation of the on-axis power content of the light distribution at the focal area. According to theoretical considerations,[...]texto impreso
Martínez Herrero, Rosario ; Carnicer, Artur ; Juvells, Ignasi ; Sanz Ortiz, Ángel Santiago | The Optical Society Of America | 2020-09-29In the analysis of the on-axis intensity for a highly focused optical field, it is highly desirable to deal with effective relations aimed at characterizing the field behavior in a rather simple fashion. Here, a novel and adequate measure for th[...]
