Abstract

The invention discloses a production method for a liquid-core optical fibre and quartz optical fibre coupling device, which belongs to the technical field of optics, and aims at solving the problems of poor firmness, rough packaging and high loss of an existing producing method for liquid coupling by the liquid-core optical fibre and quartz optical fibre coupling device. The production method comprises the following steps: producing two pores in the both ends of one hollow optical fibre by a femtosecond micromachining device; flatly cutting the end surface of one end of each of two quartz optical fibres and the end surfaces of the both ends of the hollow optical fibre respectively by utilizing an optical cutting knife; welding and communicating the both ends of the hollow optical fibre with the flat surface ends of the two quartz optical fibres respectively by a welding machine; moving a first tee joint and a second tee joint to the first open pore and the second open pore respectively; fixing the both ends of each of the first tee joint and the second tee joint on the hollow optical fibre respectively by screws; vacuumizing the hollow optical fibre; and then starting a liquid pressurization device to inject a liquid from the third end of the first tee joint until the hollow optical fibre becomes a liquid-core optical fibre fully filled with the liquid, thus finishing production for the liquid-core optical fibre and quartz optical fibre coupling device. The production method can be used for optical fibre networks for optical fibre communication, optical fibre sensing and the like.

Description
