As a new type of optical fiber that overcomes the limitations of conventional glass-core fibers, hollow-core fibers—which confine light in air through photonic bandgap and anti-resonant effects—are attracting significant attention. In this paper, we describe the fundamentals of hollow-core fibers, the current state of the technology, and prospects for their social implementation.
