Polarized-light optical actuation in amorphous chalcogenides: dynamic studies

摘要

The presented research relates to the dynamic studies of the so-called optomechanical effect in chalcogenide glasses. We present a novel study of a dynamic response of the atomic force microcantilever balance and chalcogenide glass upon illumination with alternating polarized light up to the resonant frequency of the cantilever. The sharp response peak of the microcantilever system was found at frequencies around ~22.7 kHz, however, the origin of the effect remains speculative. Nevertheless, it has been demonstrated that the cantilever-chalcogenide glass reliably responses to the polarized light change up to a frequency of ~5 kHz (200 μsec) or possibly faster.
