Where are you from and where did you study before coming to School of ICT?

– I am originally from a small suburb in Mumbai (Bombay), India. I hold a Bachelors degree in Electronics Engineering from the University of Mumbai. Then I followed it up with a Masters in Electrical Enginering (specialization in Photonics) at KTH and a short research stint at the Optoelectronics Research centre (ORC) based in the University of Southampton (UK) before coming back to KTH for pursuing the PhD.

What is your topic and why did you choose it?

– My thesis is titled ‘Effects of surface plasmons on subwavelength metallic structures’. It falls under the broad area of metal optics which provides an amazing opportunity to integrate electronics and optics at the nanoscale. I got acquainted and subsequently interested by metal optics and plasmonics during my time at the ORC.

Describe your topic in short

– My work deals with the study of novel optical properties (scattering, absorption, birefringence) exhibited by artificial materials called ‘metamaterials’ , understanding the physics of light interaction with them and exploring some of their practical applications in detail. The fundamental components  of metamaterials are metallic structures that are much smaller in size than the wavelength of incident light.

Tell us something about your results

– An efficient robust refractive index sensor for lab-on-chip applications using perforated metallic films is presented. I have also designed a metamaterial that can provide a negative refractive index with least losses in the telecommunication range of wavelengths that can be prospectively used to construct high-resolution lenses. Near-field coupled nanoparticle-based systems that can slow light by a factor of a few tens are studied and analyzed. A concerted effort is made to understand and simplify the physics of light-metallic structure interaction of all the above structures.

What will the future briPhng for your research topic?

– Efficient sensing of chemical and biological matter using a simple excitation set-up, constructing high-resolution super lenses, slowing light by a substantial factor and moving towards realization of a dynamic optical buffer that can revolutionize communication.

How does your future plans look like?

– I would like to work as research engineer either in the industry or academia located in Denmark or South of Sweden for now.
