S. Dutta Gupta

I am a superannuated faculty of University of Hyderabad, where I served for more than three decades. Currently most of my research and teaching activities are at TIFR Hyderabad. My main research interests are in theoretical optics, plasmonics, nano-optics, quantum and nonlinear optics. I have a very a strong collaboration with theoretical and experimental groups at TIFR Mumbai, IACS Kolkata and IISER Kolkata. I have worked on different facets of optics ranging from single atom lasers, fast and slow light, PT-symmetric systems, etc to reflectionless potentials. Along with my IISER Kolkata colleagues I have authored a book designed to motivate young researchers in modern trends in optics. I authored a US Patent in collaboration with G S Agarwal. My current research interests focus on

• Spin-Orbit interaction in structured optical fields and vector beams
  (collaboration with IISER Kolkata team)
• Transverse spin in tight focusing in a tilted optical tweezer
  (collaboration with IISER Kolkata team)
• Berreman modes and Bound States in Continuum in optical systems
  (collaboration with TIFR, Mumbai team)
• Negative index behavior in polar molecules and correlated photon lasers
  (collaboration with IACS Kolkata team)

Some of my earlier projects were funded by DST and CSIR.
