Strong localization of whispering gallery modes in an optical fiber via asymmetric perturbation of the translation symmetry

Recently introduced Surface Nanoscale Axial Photonics (SNAP) is based on whispering gallery modes circulating around the optical FIber surface and undergoing slow axial propagation. In this paper we develop the theory of propagation of whispering gallery modes in a SNAP microresonator, which is formed by nanoscale asymmetric perturbation of the FIber translation symmetry and called here a nanobump microresonator. The considered modes are localized near a closed stable geodesic situated at the FIber surface. A simple condition for the stability of this geodesic corresponding to the appearance of a high Q-factor nanobump microresonator is found. The results obtained are important for engineering of SNAP devices and structures.

Optical trapping with superfocused high-M2 laser diode beam

Many applications of high-power laser diodes demand tight focusing. This is often not possible due to the multimode nature of semiconductor laser radiation possessing beam propagation parameter M2 values in double-digits. We propose a method of 'interference' superfocusing of high-M2 diode laser beams with a technique developed for the generation of Bessel beams based on the employment of an axicon fabricated on the tip of a 100 μm diameter optical fiber with highprecision direct laser writing. Using axicons with apex angle 140º and rounded tip area as small as 10 μm diameter, we demonstrate 2-4 μm diameter focused laser 'needle' beams with approximately 20 μm propagation length generated from multimode diode laser with beam propagation parameter M2=18 and emission wavelength of 960 nm. This is a few-fold reduction compared to the minimal focal spot size of 11 μm that could be achieved if focused by an 'ideal' lens of unity numerical aperture. The same technique using a 160º axicon allowed us to demonstrate few-μm-wide laser 'needle' beams with nearly 100 μm propagation length with which to demonstrate optical trapping of 5-6 μm rat blood red cells in a water-heparin solution. Our results indicate the good potential of superfocused diode laser beams for applications relating to optical trapping and manipulation of microscopic objects including living biological objects with aspirations towards subsequent novel lab-on-chip configurations.

Antecedentes artísticos de la danza "contact improvisation": visiones educativas de los "contacters"

Esta investigación tiene como objeto realizar un estudio de la danza Contact Improvisation (en adelante CI), teniendo en cuenta los antecedentes artísticos; considerar las visiones educativas de los contacters (personas que practican CI); y valorar las posibilidades de la danza CI, considerándola como herramienta útil para la educación. El CI es un envolvente sistema de movimiento iniciado en 1972 por el coreógrafo americano Steve Paxton. Una danza improvisada que se basa en la comunicación entre dos cuerpos que están en contacto y combinan la relación con las leyes físicas que gobiernan el movimiento – gravedad, impulso e inercia. La inquietud de encontrar nuevos caminos que ayuden al desarrollo de una educación más integral partiendo de procesos diferentes a los habituales, es lo que ha motivado este estudio; para ello, se pretende utilizar formas artísticas que aboguen y fomenten la libertad, la sensibilidad y la comunicación de forma creativa. En concreto, buscamos en el CI aspectos que sean favorables para una educación que, a diferencia de la educación reglada, le dé más importancia al desarrollo de la inteligencia emocional...
