Fabry-Perot Filter Constructed with Anisotropic Space Layer and Isotropic Mirrors

Abstract

In this study a new design concept of the Fabry-Perot filter, constructed with an anisotropic space layer and a couple of isotropic mirrors, was proposed based on the Maxwell equations and the characteristic matrix method. The single-and double-cavity Fabry-Perot filters were designed, and their optical properties were investigated with a developed software package. In addition, the dependence of the transmittance and phase shift for two orthogonal polarization states on the column angle of the anisotropic space layer and the incidence angle were discussed. We demonstrated that the polarization state of electromagnetic waves and phase shifts can be modulated by exploiting an anisotropic space layer in a polarization F-P filter. Birefringence of the anisotropic space layer provided a sophisticated phase modulation with varied incidence angles over a broad range, resulting in a wide-angle phase shift. This new concept would be useful for designing optical components with isotropic and anisotropic materials.

The design and preparation of a Fabry-Pérot polarizing filter

“…For this reason, we design a double-cavity FP polarizing filter with the stack Substrate/(HL) 5 H 2N (HL) 5 H L (HL) 5 H 2N (HL) 5 H/air and numerically investigate the optical properties as well as the angular-selective performances of the filter. [16] Figure 4 displays the transmittance and phase shift of the designed doublecavity filter at normal incidence. As seen in Fig.…”

Homogeneity analysis of sculptured thin films deposited in symmetric style through glancing angle deposition technique

“…[12,13] Their applications are also greatly anticipated. [14] Numerous kinds of optical components with STF have been successfully manufactured, such as phase-retardation devices, [15] polarizationselective beam splitters, [16] polarizers, [17] sensors, [18] notch filters, [19,20] Fabry-Perot filters, [21] and three-dimensional (3D) photonic crystals. [22] For the glancing angle deposition technique (GLAD), the application of STF is normally limited by the uniformity of STF, which is ascribed to the difference in distance between substrate and evaporation source.…”
