Xinhua News Agency, Helsinki, May 13 (Reporter Zhu Haochen and Xu Qian) The University of Turku in Finland announced on the 13th that its scientific research team has developed a simple, energy-saving and low-cost new method to create "optical microcavities" to help explore a professional field in quantum science - the interaction between light and matter.

　　According to a press release issued by the university, traditionally, the manufacturing of optical microcavities relies on vacuum deposition processes, which are expensive and have high energy consumption, which has certain restrictions on the extensive development of related research. The school’s scientific research team introduced a solution treatment method, using basic dip coating, spin coating and other technologies to successfully create a fully functional optical microcavity.

　　According to reports, optical microcavity is a microstructure that can highly control the propagation and reflection behavior of light, and is widely used in cutting-edge fields such as optics, quantum physics and nanotechnology. Its core function is to enhance the interaction between light and matter, which can be used to produce polarized excitons - a special mixed particle composed of light and matter.

　　"The new method we have developed is low cost, less energy consumption and more convenient, and the optical microcavity we have built has good performance, which greatly reduces the research threshold in this field and makes it easier for scientific researchers to explore the interaction between light and matter." said Constantinos Zaskarakis, the research leader and associate professor at Turku University.

　　The communiqué said that the school's scientific researchers also managed to directly measure the light emitted by the polarization excitation element to assist in the research on the dynamics of the polarization element. The latest research results are crucial to the development of technologies such as ultra-efficiency lasers, quantum optics and next-generation displays.
