Background
The traditional optical tweezers have the defects of large volume, short working distance, difficulty in realizing multi-optical tweezers operation and the like, so that the traditional optical tweezers are difficult to be widely applied. The optical fiber optical tweezers overcome the defects and have the advantages of simple structure, low price, strong flexibility of a transmission light path, large capturing range and the like, and are more and more widely paid attention to. The fiber optical tweezers system utilizes the laser beam emitted from the processed fiber end face to realize the micromanipulation of particles. Compared with a microscope-based optical tweezer system, the optical trap formed by the optical fiber is flexible to operate and can freely move the captured biological sample. The micro-control system is simple and applicable, and the optical fiber can penetrate into the sample cell to form an optical trap, so that the trapping range of the optical trap is greatly improved. The trapping optical system is separated from the observation optical system, so that measuring equipment such as laser beam metering and a spectrometer is added in the system with a large degree of freedom. The laser input end of the optical fiber optical tweezers is in optical fiber movable connection with the semiconductor diode laser with the tail fiber, an external optical system is not needed, and the structure is particularly simple.

The main problem faced by the optical fiber tweezers with the fused biconical taper array is reasonable protection of the taper angle of the optical tweezers, and the optical tweezers are convenient to use daily while meeting the protection. However, the taper angle of the front end of the array optical fiber optical tweezers obtained after tapering is a small taper angle, so that the array optical fiber optical tweezers are extremely easy to damage after being knocked slightly, and the array optical fiber optical tweezers are very careful to use, so that inconvenience is brought to operation.
