Optical properties of molybdenum disulfide based photonic crystal

In this paper, the transmission properties of a one-dimensional photonic crystal containing molybdenum disulfide (MoS2) monolayers are studied theoretically using the transfer matrix method. The considered photonic crystal structure contains MoS2 monolayers, which are embedded between dielectric layers. It is found that the presence of MoS2 causes to creation of a new photonic band gap which is almost omnidirectional and also polarization insensitive. Besides, the spatial distribution of the tangential component of the electric field for a TE-polarized plane wave has been shown for some wavelengths. It is found that the behaviour of the waves from the MoS2 induced band gap is different from that of Bragg gaps. Finally, the Gaussian beam propagation inside and outside of the photonic crystal have been simulated using the finite element method for critical wavelengths and different incident angles which verify the behavior of field profiles.

Automated summary

This paper theoretically studies the transmission properties of a one-dimensional photonic crystal containing molybdenum disulfide monolayers and shows the creation of a new omnidirectional and polarization insensitive photonic band gap due to the presence of MoS2. The behavior of waves from the MoS2 induced band gap is found to be different from that of Bragg gaps. Gaussian beam propagation inside and outside of the photonic crystal is simulated to verify the behavior of field profiles.
