Research Plan


  • Our main research interests are Quantum imaging, random laser and inverse scattering. Quantum imaging is a sub-field of quantum optics that exploits quantum entanglement of electromagnetic waves in order to increase the image resolution beyond of classical limit. Examples of quantum imaging are quantum ghost imaging, quantum lithography, and quantum sensing. Also, it can be used to save data pattern in quantum computers. Theoretical study of quantum imaging is under investigation in our group
  • Random lasers are mirror less lasers whose feedbacks provided by multiple scattering in amplifying disordered medium. In fact random lasing is a combination of localization of electromagnetic waves and amplification in random active media. Therefore investigation of this phenomenon is important from physical point of view. We study different properties of random lasers.
  • In Optics, the inverse scattering is determining the characteristics, refractive index distribution and object shapes in different media by measuring and analyzing the scattered radiation, emitted radiation and reflection and transmission spectra. Investigation of inverse scattering is being done by our group.
