Special Issue Information

Dear Colleagues,

This Special Issue on “Micro/Nano Optical Devices and Sensing Technology” addresses a cutting-edge and rapidly evolving area at the intersection of optics, materials science, and nanotechnology.

Sensing technology within this field exploits the sensitivity of micro/nano optical devices to detect various physical, chemical, and biological parameters. In addition, micro/nano optical devices are used in optical communication systems to increase data transmission rates and reduce energy consumption. They enable the integration of multiple optical functions on a single chip, leading to more compact and cost-effective optical communication modules. The fabrication of micro/nano optical devices often requires advanced techniques such as electron beam lithography, focused ion beam milling, and self-assembly methods, which allow for the precise control of device structures and properties at the nanoscale.

In conclusion, micro/nano optical devices and sensing technology hold great promise for revolutionizing various fields, from healthcare and environmental protection to information technology, by providing highly sensitive, compact, and efficient optical solutions through the manipulation of light at the micro- and nanoscales.

With the widespread application of optical technology in numerous fields, the polarization performance of transmissive optical components has become increasingly crucial. The extinction ratio, an important indicator for evaluating their polarization characteristics, holds great significance for its precise detection. Aiming at the measurement of the extinction ratio of a transparent component, this study proposes a measurement method for solving the extinction ratio based on measuring the Mueller matrix of the transparent component. The purpose is to analyze the worst position of the extinction ratio of the transmissive component. The extinction ratio of the sample is obtained according to the phase retardation derived from the Stokes vector of the incident light and the Mueller matrix of the optical component, and a theoretical analysis and simulation of this method are carried out. The simulation results verify the feasibility of the theoretical derivation of this method. To further verify the accuracy of the measurement method, experimental verification is conducted. A standard transparent sample with a phase retardation of 13 nm is selected for actual measurement. The data of independent experiments on the transparent sample under different powers are analyzed, and the extinction ratio of the transparent sample is further obtained. When using this method, the relative error is less than 2%, indicating good accuracy. Full article
