Abstract: The invention comprises a photonic crystal fiber (PCF) assembly comprising a PCF and at least one ferrule structure. The PCF has a center axis and comprises a core region and a cladding region and a first fiber end section with a first fiber end. The ferrule structure has a center axis and is mounted to the first fiber end section. The ferrule structure comprises an inner ferrule arrangement and an outer ferrule arrangement surrounding the first fiber end section. The inner ferrule arrangement comprises an inner ferrule front section proximally to the first fiber end and an inner ferrule rear section distally to the first fiber end, and each of the inner ferrule sections have an inner diameter and in at least a length thereof fully surrounds the PCF. The inner ferrule rear section is anchored in an anchor length section to the first fiber end section and the inner ferrule front section supports the first fiber end section proximally to the first fiber end.

Abstract translation: 本发明包括光子晶体光纤（PCF）组件，其包括PCF和至少一个套箍结构。 PCF具有中心轴并且包括芯区域和包层区域以及具有第一光纤端部的第一光纤端部。 套箍结构具有中心轴线并安装到第一光纤端部。 套箍结构包括内套箍装置和围绕第一光纤末端部分的外套箍装置。 内套圈装置包括在第一光纤端部附近的内套圈前部和在第一光纤端部的远端的内套圈后部，并且每个内套圈部分具有内径并且在其至少一段长度上完全包围 PCF。 内套圈后部锚固在第一光纤端部的锚定长度部分中，并且内套圈前部将第一光纤端部支撑在第一光纤端部附近。
