Vankatraman Gopalan's research focuses on the science and technology of nonlinear optical materials. The work straddles materials science, physics, and optical engineering. There are three current areas of focus: complex oxides, semiconductor fibers and metalattices, and symmetry. Technology impacted by Gopalan's research includes: 

  • Multiferroics enable electrical control of magnetic devices, and vice versa, and dual electrical-magnetic storage media
  • Nonlinear optical devices are targeted for optical communications and infrared applications
  • The vision of hybrid semiconductor-metal-silica structures is all-fiber optoelectronics, where light generation, modulation and detection can be performed within a fiber
