At the 2025 American Society of Cataract and Refractive Surgeons (ASCRS) meeting held in Los Angeles, the top paper ...

Vertical and horizontal relative peripheral refraction (RPR) are associated with faster axial length progression and higher ...

Specifically, as shown in Fig. 3 (b), a refractive index variation of ∆n = 0.33 between air and water led to a spectral red shift of 0.12283 µm, corresponding to an impressive sensitivity of 372.21 nm ...

In this paper, we simulate a refractive index sensor based on the 2-D photonic crystal using finite difference time domain methods. The sensor which is called double-hole defect sensor, consists of ...

Great Strides in the Development of High Refractive Index Polymers for Optoelectronics Researchers report a novel family of low-cost, sustainable polymers that could be useful for modern displays, ...

FIGURE 2. (A) Unit cell schematic of the improved sensor. (B) Computed transmission spectrum for a normally incident Y-polarized plane-wave excitation of the improved sensor with air as cladding ...

The refractive index is specific to a substance, making this property an easy and efficient method to characterize materials and evaluate their purity. When the test sample is a simple mixture of two ...

SMF-PCF-SMF structure is a basic refractive index sensor unit that achieves Mach-Zehnder interference principle through fiber core mismatch. The structure is shown in Figure 1. In this paper, the ...

Then they turned to materials that were not studied for their refractive properties. The unit cell, side and top views, of the ReX 2 bulk structure. The a, b, and c are crystallographic axes marking ...
