Study of the problem of radiation coupling into non-standard optical fibers

The article is devoted to the problems of modern communications, namely – to custom experimental fibers that be used in future communication systems. We consider a non-standard optical fiber which, due to its structure, offers an advantage in multi-channel transmission via different modes. This fiber has a hollow-core structure which means that traditional light coupling methods can be not efficient. In the experimental part, the conductivity of the fiber tested by finding a solution to improve the radiation coupling into the fiber. The conclusion presents the final with the experimental results and summarizes the topic of the paper.
