“…As light is completely reflected at the interface of two different media, the Goos-Hänchen (GH) effect refers to the lateral displacement and angular deflection between the reflected light beam and the incident beam, called as the spatial and the angular GH shift, respectively. The spatial GH shift has been verified in experiment [1,2]. Generally, the spatial GH shift is relatively small, which is equivalent to the multiple of the incident wavelength.…”

The Goos-Hänchen (GH) effects are investigated for a transverse magnetic beam totally reflected by periodic PT-symmetric photonic crystals. A dielectric layer with a real refractive index situates as a defect in the center. Both positive and negative spatial GH shifts are induced around the defect mode. The GH shifts sensitively change with the refractive index of the defect layer. More importantly, giant negative GH shift effect with big reflectance could be found and modulated by increasing the gain-loss factor in PT-symmetric systems, which could improve the detecting sensitivity of the defect. Our study may be valuable in potential applications for highly sensitive sensors.

“…The GH shift is proportional to the angle-dependent phase variation when experiments are performed with a single wavelength light source. [20,[28][29][30][31] When the wavelength is modified, the derivative of the phase with re-spect to the incident angle varies consequently. Thus, a large GH shift can also be generated by changing the wavelength.…”

“…Many studies have demonstrated that the GH shift is closely related to the partial derivative of the reflection phase with respect to the incident light angle when the GH shift is investigated by the stationaryphase approach. [20,[28][29][30][31] The GH shift can reach its maximum when the rate of phase variation is maximum. Because GH shift detection is the measurement of relative position, it is not affected by optical common-mode noise and has a higher signal-to-noise ratio than optical intensity detection.…”

This paper puts forward a novel method for measuring the thin period-structure-film thicknesses based on the Bloch surface wave (BSW) enhanced Goos-Hänchen (GH) shift in one-dimensional photonic crystal (1DPC). The BSW phenomenon presented in 1DPC enhances the GH shift generated in the attenuated total internal reflection structure. The GH shift is closely related to the thickness of the film which composed by layer-structure of 1DPC. GH shifts in multiple different incident light conditions will be obtained by varying the wavelength and angle of the measured light, and the thickness distributions of the entire structure of 1DPC will be calculated by the Particle Swarm Optimization (PSO) algorithm. The relationship, between the structure of a 1DPC film composed of TiO2 and SiO2 layers and the GH shift, is specially investigated. Under the specific photonic crystal structure and incident conditions, a giant GH shift, 5.1 × 103 times of the wavelength of incidence, can be obtained theoretically. Simulation and calculation results show that it is capable to measure the thicknesses of termination layer and periodic structure layers of 1DPC films with 0.1 nm resolution by measuring the GH shifts. The exact structure of a 1DPC film is innovatively measured by the BSW enhanced GH shift.

“…One-dimensional photonic crystals (1DPC) which has the characteristic of incomplete photonic band gap (PBG) can be used as a sensitive membrane layer for refractive index sensing to replace the metal film in the surface plasmon resonance (SPR) sensor and solve the problem of strong absorption of light by SPR [1][2][3]. In order to avoid the influence of the environmental noise and improve the system stability, the Goos-Hä nchen shift (GHS) which can be greatly enhanced by PBG edge and Bloch Surface Wave (BSW) was selected as the direct measurement object instead of the reflected light intensity [4][5][6]. GHS is extremely sensitive to the change rate of the reflection coefficient of the reflection membrane, and the PBG and BSW effects of 1DPC reflection membrane can lead to drastic changes in the reflection coefficient [7][8][9][10].…”

The Goos-Hä nchen shift (GHS) can be measured typically by fixing the wavelength of incident light and changing the angle of incidence to analyze the optical modulation characteristics of the film material or its relevant parameters. In this paper, the membrane structure of one-dimensional photonic crystals (1DPC) was analyzed by varying the wavelength of incident light combined with GHS measurements. The theoretical analysis and experimental results show that the spectrum-GHS analysis method can show the band gap of 1DPC well and enhance the GHS, so as to improve the sensitivity of the prism-type sensors with 1DPC film sensitive layer. The abstract summarizes key findings in the paper.
