Optomechanical microcavities are extremely small structures with diameters of less than 10 micrometers (about a tenth of a human hair) inside which light and mechanical vibrations are confined. Thanks to their small size and to efficient microfabrication techniques that enable them to hold intense light energy and interact with mechanical waves, microcavities can be used as mass and acceleration sensors and in Raman scattering (a spectroscopy technique deployed to analyze materials, including [...]

Microcavidades optomecânicas
Com dimensões inferiores a 10 micrometros, essas microcavidades absorvem altíssimas intensidades de energia luminosa, que ficam circulando dentro delas – a luz fica “presa” – e interagem com ondas mecânicas de forma muito eficiente.
Isso possibilita seu uso como sensores de massa, sensores de aceleração e em espalhamento Raman (espalhamento da luz pela matéria), uma técnica que [...]
