1- Nanoplasmonic Anti-counterfeiting Labels 

In this project, arrays of anisotropic nano-apertures dry-etched in a thin film of Al were employed for creating full-color anti-counterfeiting images.

Because of the polarization selectivity in the anisotropic structure, it was possible to write a set of independent data/image on a single sample.

2- Plastic Lasers for Biosensing

In this project, a combination of an organic laser and a hydrogel recognition layer was used for fabrication of photonic biosensors which can be used for Environmental Monitoring, Biomedical Applications, and Industrial Safety.

3-Nanolasers

 A new type of nanolasers was developed by doping core-shell nanoplasmonic particles into a thin film of a gain medium.
