We present a novel technique in which a reflection scanning near-field optical microscope (SNOM) is used for direct writing of nano-scale patterns into hydrogen-passivated silicon surfaces. The reflection SNOM is operated as a combined shear-force/near-field microscope enabling simultaneous imaging of topographical and optical properties with subwavelength resolution. ... Beside high resolution optical imaging (<50 nm) and patterning of hydrogen-passivated silicon surfaces, the SNOM can also be used for transferring nano-scale patterns into ordinary photo resist with a typical resolution of 50-100 nm. The SNOM thereby overcomes the far-field diffraction limit of conventional photolithography. 5, record 1, English, - scanning%20near%2Dfield%20optical%20microscope

Near-field scanning optical microscope [...] In this case the standard AFM [atomic force microscope] cantilever is replaced by something that can act as a waveguide for light (typically an optical fibre). Light is passed through the waveguide onto the sample and resulting light is detected via various means ... 3, record 1, English, - scanning%20near%2Dfield%20optical%20microscope

Microscope optique à balayage à champ proche. Il est possible d'éviter la limitation de résolution due aux conditions d'Abbe pour caractériser plus finement la microgéométrie de surface. Grâce à une fibre optique, on éclaire la surface par un très fin pinceau en incidence évanescente et l'on recueille la lumière diffractée; en balayant la surface on construit ainsi une image point par point. 1, record 1, French, - microscope%20optique%20%C3%A0%20balayage%20%C3%A0%20champ%20proche

[...] a principios de 1980 se inventó el microscopio óptico de barrido de campo cercano (SNOM o NSOM), en el que una fuente de luz nanoscópica, generalmente una punta de fibra óptica con una apertura más pequeña de 100 nm, barre la superficie de la muestra en la región llamada "campo óptico cercano". 2, record 1, Spanish, - microscopio%20%C3%B3ptico%20de%20barrido%20de%20campo%20cercano

Estos microscopios rastrean la muestra mediante un haz de luz que se emite (o se recibe, según el diseño) a través de una pequeña abertura situada en el extremo de la punta de la sonda, que no es más que una pequeña fibra óptica cubierta de un metal que refleja la luz y evita pérdidas. El diámetro de la abertura y la distancia sonda-muestra tienen dimensiones similares e inferiores a la longitud de onda de la luz que se emplea. 3, record 1, Spanish, - microscopio%20%C3%B3ptico%20de%20barrido%20de%20campo%20cercano

It is important to establish fabrication technologies for nanostructures as well as nanometer-scale optical characterizations. The selective growth technique and Stranski-Krastanow growth for the nanostructure fabrication, demonstrating natural ordering of InGaAs quantum dots on multi-atomic steps without any lithographic processing, will be discussed. Photoluminescence from a single quantum dot and direct observation of two dimensional electron motion in point contact structures are also discussed using the far-field optical microscope and the near-field optical microscope. 1, record 2, English, - near%2Dfield%20optical%20microscope

On pourrait croire que, dans cette course vers la visualisation de l'infiniment petit, la microscopie optique ait baissé les bras, handicapée qu'elle était par le phénomène de la diffraction de la lumière. Comme nous allons le voir, il n'en est rien, et de très prometteuses perspectives s'ouvrent avec le développement d'un nouveau type de microscope : le microscope à champ proche, dont le principe est l'analyse du champ lumineux à une très faible distance de la surface étudiée, constitue aussi pour l'optique un virage conceptuel important. 4, record 2, French, - microscope%20optique%20%C3%A0%20champ%20proche

La pénétration dans l'air des ondes évanescentes permet d'envisager l'observation à une distance plus grande qu'avec les autres microscopes à sonde locale, qui opèrent pour la plupart à quelques angströms de la surface. Cela peut être pour étudier des surfaces très irrégulières ou présentant des dénivellations importantes (circuits intégrés par exemple). 3, record 2, French, - microscope%20optique%20%C3%A0%20champ%20proche
