Special Issue Information
Dear Colleagues,
The interplay among optics, thermics and mechanics is of paramount importance for technological applications. For instance, in devices exploiting electromagnetic radiation, such as antennas, it is crucial to control the working temperature in order to avoid overheating or system damages. On the other hand, light can be exploited to apply forces and deformations at the micro- and nanoscales. For instance, optical tweezers have been introduced to trap sub-micrometric objects into highly focused laser beam. The aforementioned applications are just a few examples of the plethora of applications in which the opto-thermo-mechanical interaction is crucial.
Metallic and dielectric nano-objects and metasurfaces proved very useful to concentrate light and to enhance the electromagnetic field. These geometries are the perfect playground where the opto-thermal and the optomechanical interactions may be sought. As withnessed by the very recent and high impact publications in this field, the opto-thermo-mechanical interactions in nano-objects and metasurfaces still pose puzzling questions, and several challenges remain to be explored for the design and realization of next-generation optical devices.
The scope of this Special Issue is to tackle recent and promising achievements in the field of linear and nonlinear opto-thermo-mechanical interactions in nano-objects, metamaterials and metasurfaces of nanostructures. We are also open to new materials that can be patterned and exploited for nanostructures engineering. Areas to be covered may include, but are not limited to, the following:
- Opto-thermal and opto-mechanical processes;
- Optical limiters and switch;
- Tunability of the optical properties by using phase changing materials;
- Optical tuning with liquid crystals;
- Multiphysics modelling;
- Experimental techniques to address the opto-thermo mechanical processes ;
- Higher-harmonic, sum frequency and difference frequency generation modulated by external optical pulses;
- Photo-injection for all-optical control;
- Thermo-mechanical tuning of the Raman spectrum emitted by nanostructures;
- Light induced thermo-mechanical tuning in metamaterials and nano-objects;
- Dynamic control of nonlinear optical processes in metasurfaces.
