    摘要： A photonic crystal fiber (PCF) assembly including a PCF and at least one ferrule structure. The PCF includes a core region and a cladding region and a first fiber end section with a first fiber end. The ferrule structure is mounted to the first fiber end section. The ferrule structure includes an inner ferrule arrangement and an outer ferrule arrangement surrounding the first fiber end section. The inner ferrule arrangement includes 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 sections has 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.

    摘要： An optical receptacle includes: a first optical surface configured to allow, to enter the optical receptacle, light emitted from the photoelectric conversion element package, or emit, toward the photoelectric conversion element package, light travelled inside the optical receptacle; a second optical surface configured to emit, toward the optical transmission member, the light travelled inside the optical receptacle, or allow, to enter the optical receptacle, light emitted from the optical transmission member; a cylindrical part configured to house at least a part of the photoelectric conversion element package such that the first optical surface and the photoelectric conversion element face each other; and a first groove part disposed at a periphery of the first optical surface.

    摘要： Aspects of the disclosure are drawn to methods for producing a fused connector termination. An exemplary method may include setting a specification requirement to be met by the fused connector termination and applying an amount of heat to a proximal region of an unfused connector termination. The proximal region of the unfused connector termination may include an inner optical fiber coaxially positioned within an outer ferrule, and applying the amount of heat may at least partially fuse the optical fiber to the outer ferrule to form an at least partially fused connector termination. The method may also include imaging the proximal region of the at least partially fused connector termination and determining, based on the imaging, whether the proximal region of the at least partially fused connector termination meets the specification.
