“…In addition, above bandgap irradiation is associated with high absorption that is sufficient to induce a significant warming and even potential damage, while sub-bandgap irradiation has a negligible thermal contribution under standard irradiation power. Several proofs of the optical origin and athermal nature of photoinduced effects exist including the fact that photofluidity is more pronounced at low temperature [10] and exhibits polarization effects [19] or the formation of wavelength specific Bragg gratings [20]. Nevertheless, it has been recently suggested that the thermal contribution to the photoexpansion itself may not be negligible even for weakly absorbed light [21].…”

Abstract. An analytical model is developed to describe the phenomenon of giant photoexpansion in chalcogenide glasses. The proposed micro-mechanical model is based on the description of photoexpansion as a new type of eigenstrain, i.e. a deformation analogous to thermal expansion induced without external forces. In this framework, it is the viscoelastic flow induced by photofluidity which enable the conversion of the self-equilibrated stress into giant photoexpansion. This simple approach yields good fits to experimental data and demonstrates, for the first time, that the photoinduced viscous flow actually enhances the giant photoexpansion or the giant photocontraction as it has been suggested in the literature. Moreover, it highlights that the shear relaxation time due to photofluidity controls the expansion kinetic. This model is the first step towards describing giant photoexpansion from the point of view of mechanics and it provides the framework for investigating this phenomenon via numerical simulations.

“…In the previous studies, 16,22,23,25 As 2 S 3 films were deposited onto microscope slides, which were exposed to focused linearly polarized laser beams. It was demonstrated that an isotropic expansion appears at first, which gradually transforms to an anisotropic M-shaped deformation with exposure time.…”

“…21 The other is a photoinduced anisotropic M-shaped deformation in As 2 S 3 films. 16,22,23 Both of these phenomena are induced by illumination of linearly polarized band gap light. On the other hand, the OM effect appears only during illumination, i.e., it is transitory, while the anisotropic deformation exists in quasistable after illumination.…”

The optomechanical effect and photoinduced anisotropic deformation induced by illumination of linearly polarized light have been comparatively studied for glassy As 2 S 3 and Se films. The two materials show qualitatively the same behaviors in the mechanical effect and the deformation, which suggests that these photoinduced phenomena are inherent to the covalent chalcogenide glass. But, the two phenomena show different dependences upon intensity, spectrum and exposure time of excitation light, which imply different underlying mechanisms.
