The article proposes a method for measuring the refractive index using goniometric system that does not require prism angle, which simplifies measurement process compared to widely used methods of minimum deviation and autocollimation. This can be measure samples in form triangular prisms visible, ultraviolet infrared ranges. To implement method, was used. obtain reflection refracted beam, fixe...

The emergence of ultrasonic vibration–assisted polishing technology has effectively improved the machining accuracy and efficiency hard brittle materials in modern optical industry; however, material removal mechanism (UVAP) still needs to be further revealed. This paper focuses on glass (BK7), application axial vibration, atomization slurry; model was established. Based analysis relationship b...

Efficient nonlinear frequency conversion, such as second-harmonic generation in ultracompact structures, is essential for the development of modern nanophotonic devices. Here, we demonstrate intense emission scalable embedded Ag nanoparticle arrays fabricated by ion implantation into BK7 glass. The interparticle coupling effect significantly enhances local field at nanogap (gap size ? 1 nm) two...

This paper presents a multi-layered Kretschmann configuration-based Surface Plasmon Resonance (SPR) biosensor for the detection of urine glucose. The modelling, simulation, and analysis have been done by using Silver (Ag) Gold (Au) layer on low refractive index prism BK-7 separately, which created two structures: structure-I (BK7/Ag/Bio-sample) structure-II (BK7/Au/Bio-sample). Urine samples fr...

Surface roughness is a significant parameter which determines the efficiency of optical components. Surface damages induced by grinding strongly influence the mechanical strength and optical quality of optical glasses. It is meaningful to rapid evaluate the surface roughness through the measurement of different grinding parameters. In this study, a cup diamond wheel (D64) is used in grinding pr...

A novel dielectric multilayer platform sustaining Bloch surface waves is investigated for integrated photonic chips. These surface waves can be manipulated by two dimensional dielectric optical components patterned on top of the platform. We study the properties of high refractive index materials (TiO2) as active top layer of platform. Concept The Bloch surface waves (BSWs) are surface electrom...
