Our research aims at developing Optical Fiber Components, Photonics Circuits and Devices for applications in communication and sensors. My PhD research led to the technology development of fabrication and modelling of all-fiber 2x2 coupler based branching components, e.g., splitters, WDM/DWDMs, WFC, loop-mirror reflector, wavelength interleaver. In the later stage, a major focus paid to developing FD based field-convergence algorithm to analyse propagation characteristics in arbitrary and complex RI-profile waveguides and fibers. Some of the research works accomplished in the recent past involved designing all-fiber nonlinear and active devices, namely, doped fiber amplifiers, lasers and supercontinuum sources in visible and mid-IR regions using microstructure fibers, PCFs, binary multi-clad fibers as the host of the devices. Our recent research involves experimental demonstration and analytical modelling of light propagation in few mode fibers, namely vector beam generation, analysis of polarisation propagation in few-mode assisted sagnac, stress measurement, coated few-layer few-mode fibers for humidity measurement. We recently demonstrated experimentally a unique concept of fiber-cantilever beam deflection magnetometer for measurement of very low (~1 mT) magnetic field. Anisotropic and differential interference imaging are also ongoing research in our optical waveguide & photonics labs.
