Fabrication and study of femtosecond laser micromachined few-mode elliptical core waveguides
Prajal Chettri, Shailesh Srivastava
Femtosecond laser micromachining (FLM) fabricated waveguides inherently form elliptical cores due to differences in focal spot size and the Rayleigh range of the microscope objecti…

Time Dependent Third Order Nonlinear Optical Susceptibility Tensor Components of the Carbon Disulfide Molecule using Femtosecond Degenerate Four-Wave Mixing
Prajal Chettri, Shailesh Srivastava
We report time resolved studies and measurement of all the components of the third-order nonlinear optical susceptibility of CS2 at 515 nm using degenerate four wave mixing. The us…
