The dynamic interaction between light and matter presents intriguing scenarios where light can be harnessed to adjust and manipulate the form and properties of objects. Specifically, in materials and systems endowed with optical absorption, light can dissipate and generate heat, consequently leading to an increase in system temperature. Consequently, thermal expansion of the system may occur. Simultaneously, light can impart optical momentum to the matter. Owing to these phenomena, light can be utilized to regulate the temperature, shape, and positioning of nano-objects. Moreover, the interplay between optics and thermodynamics can be utilized to induce a phase transition in systems featuring phase-change materials, resulting in a reversible or permanent alteration of properties within the system through the utilization of a light source.
Main research topics:
- Opto-thermics
- Opto-mechanics
- Optically induced phase change in nanoscale systems featuring phase-change materials (e.g. VO2, GST, etc.)
- Optical tunability
- Optical deformation of nano-structures.
