“…However, the use of such microscope keeps growing during the last 10 years especially due to its ability to make very local detection of the light distribution surrounding very small samples. Thus, quantum dots [3][4][5][6], photonic crystals [7][8][9][10][11][12][13], or nonlinear materials (Raman, fluorescence, ...) [14][15][16][17] are currently characterized thanks to optical near-field microscopes working with conventional tips (coated or uncoated tapered optical fibers). Apertureless nearfield optical microscopes are often used by exploiting the tip effect, also named the "antenna effect", that leads to a large light confinement at the tip apex (see [18] and references therein).…”

International audienceAbstract We theoretically demonstrate the possibility of obtaining nanosources through an original schema based on the generation of the radially polarized surface plasmon mode of a cylindrical metallic tip. This mode has no cutoff radius and can propagate along the tip walls until its nanometric-sized apex. Instead of radiating from the tip end, the guided mode will give rise to a nanospotlight via the well-known antenna effect. 3D calculations demonstrate that both surface plasmon-guided mode and antenna effect are directly involved in the light confinement. Near-field optical microscopy can benefit significantly from this kind of probe because the sample does not need to be directly illuminated

“…These include using heaters to achieve thermo-optic tuning [4,5], and pore infiltration by liquids [6], polymers [7] or liquid crystals [8] to achieve a broad tuning range. The progress in micrometer-scale integrated optics has led to an increase in attention for mechanical tuning [9][10][11][12]. Mechano-optical interactions have been utilized in for example sensor [13] and actuator [14] applications to modulate the evanescent field.…”

Abstract:We show that nano-mechanical interaction using atomic force microscopy (AFM) can be used to map out mode-patterns of an optical micro-resonator with high spatial accuracy. Furthermore we demonstrate how the Q-factor and center wavelength of such resonances can be sensitively modified by both horizontal and vertical displacement of an AFM tip consisting of either Si 3 N 4 or Si material. With a silicon tip we are able to tune the resonance wavelength by 2.3 nm, and to set Q between values of 615 and zero, by expedient positioning of the AFM tip. We find full on/off switching for less than 100 nm vertical, and for 500 nm lateral displacement at the strongest resonance antinode locations.

“…By use of refractive index matching liquid [19] with a refractive index of 1.483, a near-field scanning optical microscope (NSOM) image of the intensity distribution of the stationary wave field of the Ag layer surface was taken within a 1 m × 1 m area in the Y-Z plane chosen at random as shown in Figure 5, and the stationary wave field shows periodic distribution with a period of 85.0 nm along the Z-axis, in good agreement with the theoretical value 80.1 nm.…”

A new sub-micron photolithography tool has been realized by utilizing the interference of surface plasmon waves (SPWs) on the near surface of a silver (Ag)-clad ultraviolet (UV) planar waveguide. A laser beam with a wavelength of 325 nm was incident into the waveguide core, and suffered a series of total internal reflections on the interfaces between the waveguide core and the cladding layers. The incident light and the reflected light induced two beams of SPWs traveling in contrary directions, which interfered with each other and formed a standing wave as a sub-micron photolithography tool. A near-field scanning optical microscope (NSOM) was employed to measure the intensity distribution of the stationary wave field of the near surface of the Ag layer of the waveguide, anastomosed with theoretical values acquired by use of finite difference time domain (FDTD) simulations. And with this sub-micron photolithography tool a SMG with a period of 79.3 nm, in good agreement with the theoretical value of 80.1 nm, was inscribed on the surface of a self-processing hybrid SiO 2 /ZrO 2 solgel film for the first time.surface plasmon waves (SPW), silver (Ag)-clad planar waveguide, solgel, sub-micron lithography
