Comparative Study of the One Dimensional Dielectric and Metallic Photonic Crystals

Abstract

The optical transmission properties of two types of photonic crystals have been analyzed by using the transfer matrix method. The first one is the dielectric photonic crystal (DPC), and the second is the metallic photonic crystal (MPC). We found the dielectric and metallic photonic crystals have different transmission spectra. The effect of the most parameters on the transmission spectra of the dielectric and metallic photonic crystals has been studied.

Two-Dimensional Layered Nanomaterial-Based One-Dimensional Photonic Crystal Refractive Index Sensor

“…Hence, the sensitivity order should be: graphene > WS 2 > WSe 2 > MoSe 2 > MoS 2 , which is the opposite of the absorbance order; graphene < WS 2 < WSe 2 < MoSe 2 < MoS 2 [ 15 ]. However, in the case of 1DPC this order of sensitivity may be disturbed because of the reflection [ 16 ] or transmission [ 17 ] spectrum of the sensor, which depends on the pitch and thickness of the stacked layers. The obtained sensitivity for the case of silicon is: graphene > WSe 2 > WS 2 > MoSe 2 > MoS 2 .…”

“…Hence, the sensitivity order of these layered nanomaterials should be: graphene > WS 2 > WSe 2 > MoSe 2 > MoS 2 . However, in the case of 1DPCs this order of sensitivity may be disturbed because reflection [ 16 ] or transmission [ 17 ] depends on the periodicity and thickness of the composite layers.…”

Characterization of one dimensional liquid crystal photonic crystal structure

“…The electromagnetic mode of a frequency within the photonic bandgap (PBG) cannot propagate through the PhCs due to the reflection and refraction at the boundaries of the alternating materials [1][2][3]. However, the allowed modes have high transmission through the PhC structure.…”

Straightening of light in a one dimensional dilute photonic crystal

“…In case if the photon's wavenumber k x lies in the photonic band gap region, the transmission coefficient must be suppressed (see, for example, Ref. 15 ). Next, imagine that the same photon falls down onto the system obliquely, as shown in Fig.1 and assume that the transversal to plates component k x still remains in the photonic band gap.…”
