Abstract

A random laser structure is proposed in which we symmetrically embed a toroidal waveguide in the randomly distributed scattering particles. The finite difference time domain (FDTD) method is used to numerically simulate the distribution of the optical filed in the random scattering system embedded with a toroidal waveguide and the corresponding comparative structures

and the modes spectra of each structure are obtained. The results show that there only exists a narrow linewidth lasing emission in the center of system

which verifies that the presence of the toroidal waveguide can influence the lasing emission of the random system

reduce the number of modes

and enhance the lasing intensity to a certain degree.
