Simulation of the mass, momentum, and angular momentum transfer due to a temporally Gaussian HE(1,1) mode light pulse in a silica fiber

Optoelastic continuum dynamics simulation of the mass, momentum, and angular momentum transfer due to a temporally Gaussian HE(1,1) mode light pulse in a silica fiber. The atomic mass, momentum, and angular momentum transfer is presented by plotting the velocities and displacements of atoms in the mass density wave driven by the light pulse. The electromagnetic energy of the pulse is 1 micro J, the wavelength is 1550 nm, and the FWHM is 27 fs. The diameter of the circular fiber core is 1550 nm. The dashed line shows the boundaries of the fiber.
