Special Issue Information

Dear Colleagues,

Photonics has been widely considered as the future alternative to accelerate the processing speed of electronics. Its fast processing speed with ultra-low power consumption encourages the researchers to find more applications in various areas.

Optical communication is a successful example of the photonic applications, which starts from the invention of optical fibers by Charles Kao and serves as the backbone of the communication network at the moment. The evolution of the optical communication has entered the era of higher order modulation format, space division multiplexing and ultra-broadband transmission, which is based on the advanced photonic technologies.

All optical signal processing enables light speed processing and is attractive in various areas. The linear and nonlinear properties of materials can be exploited to build novel functional devices. The recently emerging diffractive deep neural network is a significant trial of the advanced photonic signal processing techniques in the area of artificial intelligence (AI).

In the Special Issue of “Advanced Photonic Applications”, we encourage the colleagues in the area to submit high quality works, focusing on the modeling, simulation, design, analysis, and experimentation of advanced photonic applications to benefit the related research communities and the interested audience.

The characteristics of modern portable spectrometers based on photodetector arrays make it possible to create on their basis a new class of devices for operational control of the optical properties of various media. The introduction into the practice of diffuse reflectance spectroscopy with spatial resolution is hampered by the lack of an analysis of the influence of the width of the spectral region used and other sources of measurement uncertainty on the unambiguous determination of the optical properties of finely dispersed scattering materials. This article describes a method of determining the coefficient of local diffuse reflection and calculating the spectral parameters of the reduced scattering and absorption of radiation based on the differences in their shape, which are clearly manifested in a wide range of the spectrum. This allows the reduction in the determination of the desired spectral dependencies to the formation of a residual function that requires varying the values of only two parameters. A method for normalising the recorded spectral dependencies is described, which makes it possible to minimise the influence of the spectral characteristics of the equipment used on the recorded spectral–spatial profiles. Approbation of the method was carried out on examples of processing spectral–spatial diffuse reflection profiles of four samples of finely dispersed scattering structural materials, as well as diffuse reflection profiles of living tissue in the palm thenar region. The sources of uncertainty that affect the uniqueness of the obtained solutions are found, and solutions are proposed to minimise their influence on the desired spectral dependencies. The results obtained indicate the prospects of using the described method for creating equipment for non-destructive control of the optical properties of finely dispersed materials and media, including living tissues and food products.
