Optical device having liquid-core optical fiber and method for producing such a device

摘要

The connection device for liquid-core optical fiber comprises a sleeve traversed by a channel comprising a plurality of communicating stacked conduits, a first conduit being formed from an end of the sleeve and being arranged to receive, in a sealed manner, at the corresponding end of the sleeve, one end of the optical fiber, and a second conduit being formed communicating with the first conduit, and closing means that hermetically seal the end of the second conduit opposite the end that communicates with the first conduit, the sleeve further having a third conduit for filling the internal volume of the second conduit when the latter is closed at one end by the closing device and the fiber is inserted into the first conduit, the third conduit transversely connecting the outside of the sleeve with the inside of the second conduit, and a sealing plug for hermetically sealing the port of the third conduit opening to the outside of the sleeve.

主权项

1. An optical device having liquid-core optical fiber, comprising:
at least one first connecting device comprising:
a sleeve of tubular structure through which a channel comprising a plurality of superposed and communicating ducts passes, a first duct being formed from one end of the sleeve and being arranged to receive hermetically at the corresponding end of the sleeve one end of the optical fiber, and a second duct being formed communicating with the first duct; andclosing means hermetically closing that end of the second duct which is opposite the end communicating with the first duct,wherein the sleeve further contains a third duct intended for filling the interior volume of the second duct when the latter is closed at one end by the closing device and the fiber is inserted into the first duct, the third duct connecting transversely the exterior of the sleeve to the interior of the second duct;a hermetic closing cap for hermetically closing the orifice of the third duct opening onto the exterior of the sleeve;a liquid-core optical fiber a first end of which is inserted into the first connecting device,wherein the interior volume of the second duct of the first connecting device comprises the liquid and a gas bubble and the third duct of the first connecting device is hermetically closed by the closing cap.
