My main area of research interest is Photonics integrated Circuits, both theoretical and experimental, with application to optical communications and optical sensors. My emerging interest is in the areas of optical biosensors and quantum photonics.


I graduated from New Science College, Hyderabad, with B Sc( Hons) in physics,. I did my ME (Integrated) from ECE Dept, IISc, and PhD also from IISc in the faculty of Engineering. My Ph D was on Application of coupled mode theory to fiber and integrated optic waveguide structures, under Prof A Selvarajan.


Later I went as Post Doctoral Research Fellow to Toyohashi Univeristy of Technology, Japan, during 1992-98. There my work was on tapered optical waveguide couplers and integrated optical amplifiers.


I have involved in several academic and professional activities. Recently I have been the Chairman GATE, IISc Zone (2011-13), member of NBA (2010-present), besides acting as reviewer to several journal and conferences, notably IEEE PTL, J of modern optics, JOSA, Sadhana, current science, etc.


I got involved in some sponsored research projects like, national program on smart structures (NPMASS) & systems, national program on micro-optics and nano photonics (NPMN). In IISc we have formed a formal interest group called Applied Photonics Initiative.


I took part in many national and international conferences, notably, bi-annual Photonics conference in India, ICUMT, IEEE Sensors, OFC, etc Recently, I was the General chair to International conference on optical engineering (ICOE) organized under IEEE Photonics society with the support of VTU Belgaum.


I am active volunteer of IEEE Bangalore Section, currently chapter co-ordination chair. I also chair the IEEE COMSOC chapter Bangalore Section and secretary of IEEE photonics society chapter Bangalore Section. I have supported several IEEE society chapters an many IEEE student Branches in Bangalore Section.


I look forward to scientific and academic collaborations in my area of interest. Please visit our Applied Photonics Lab website for more information about our research, students and activities.
