Common Research Theme:
As one of the development frontiers and hotspots in the field of photonics, integrated photonics and its related technologies are regarded as the necessary path and advanced stage from photonics development to the photonics industry. Their development is the cornerstone of the development of informatization in human society. Based on the research of micro-structured optical fiber, fiber-integrated passive/active devices, and miniature fiber sensors, the Key Laboratory of In-Fiber Integrated Optics, Ministry of Education of the People's Republic of China has proposed a new concept and idea of "Fiber-Integrated Optics", and developed its supporting key technologies. The core idea of fiber-integrated optics is to integrate complex optical circuits and various optical components into a single optical fiber, and a series of new, miniature, special components, devices, and systems can be formed through fiber-integrated optics methods and technologies.
The group proposed a new method of integrating devices and optical circuits within optical fibers, using a unique group of rods and ultrasonic perforation technology to prepare pre-fabricated rods, and developed dozens of multi-core microstructured fibers with independent intellectual property rights. Afterwards, microfabrication is carried out inside or outside the fiber using techniques such as fused biconical taper and laser engraving, and multiple waveguides in the fiber are combined and interconnected to achieve in-fiber optical circuit integration.
The group proposed a variety of all-fiber combined interferometers, realized interferometers integrated within a single fiber, and solved the problem of temperature compensation in discrete optical circuits based on such interferometers.
The group constructed fiber-integrated sensing microsystems with independent functions by integrating interferometers, mirrors, optical couplers, and other devices. For example, compact multi-core fiber optic SPR sensors and miniature acceleration sensors based on multi-core fiber optic interferometers have been realized, improving the integration and stability of miniature fiber optic sensing systems
