Abstract:
Photonic crystal is a new kind of materials with photonic band gap. Although the concept has been projected about 30 years, Photonic crystals have potential applications in micro-nano photonics and quantum optics. Photonic crystals have also been widely used in information optics, multifunctional sensor and other fields. In this paper, the main characteristics of photonic crystals are introduced in detail. In addition, research progress and application of photonic crystals in the photonic crystal fiber, mirrors, filters, waveguide, low threshold, multifunctional sensor, cavity quantum electrodynamics, polarizer, quantum information processing and other fields are reviewed in details. They are compared with the traditional devices and confirmed higher performance. Finally, we believe that photonic crystals will promote a new revolution of information technology with the improvement of 3D print manufacturing technology.
