A plasmônica é a área que faz a junção entre fotônica e nanoestruturas. As implicações tecnológicas resultantes do acoplamento entre campos eletromagnéticos e oscilações eletrônicas em um material condutor fazem desta área uma das mais

We numerically analyze straight gold nanorods as element of a binary-phase metasurface working in the visible regime. The designed hologram has resonance on 640 nm and wavelength band of ~ 130 nm.

In this work, we investigate a graphene-based SOI microdonut electro-absorption resonator operating under the critical coupling condition. Good modulation depth was obtained by changing graphene’s chemical potential. This configuration results in d

We design, fabricate, and characterize a plasmonic color filter with a transmission bandwidth smaller than 20 nm and an efficiency around 80%. The filter was fabricated using an Al2O3 film by interferometric lithography.

The standard charging process for polymer ferroelectrets, e.g., from polypropylene foams or layered film systems involves the application of high DC fields either to metal electrodes or via a corona discharge. In this often-used process, the DC field

Moduladores espaciais de luz são elementos que fazem a modulação de uma frente de onda de modo a resultar em uma distribuição de luz desejada. Eles operam por difração, de acordo com o princípio de Huygens-Fresnel, e por este motivo são cham

We describe the use of an interferometric system to analyze the resonance frequency of ferroelectrets. This technique is attractive (no force applied in the sample) and sensitive to small displacements, improving the analyze of elements.

We design and fabricate efficient, narrow-band, transmission color filters whose operating principle resides in a narrow-band guided-mode resonance associated with a surface-plasmon resonance. The fundamental device consists of an aluminum grating ov
