摘要： Provided are an optical fiber, which has an out-coupling characteristic of high coupling efficiency and is advantageous in terms of size reduction, and an optical signal detecting apparatus, which has a high coupling rate and high degree of integration, using the optical fiber. The optical signal out-coupling optical fiber includes: a core in which a tilted Bragg grating or a long period optical fiber grating is formed; and a cladding that surrounds the core and in which at least one V-groove that totally reflects optical signals is formed, wherein optical signals are out-coupled by using the grating and the V-groove. The optical signal detecting apparatus includes: an optical signal out-coupling optical fiber; and an optical signal receiving device monitoring or detecting optical signals emitted from the optical fiber. The optical signal out-coupling optical fiber has an in-line structure which does not require a complicated external structure, and thus can be made more compact and emit optical signals highly efficiently, and the optical signal detecting apparatus using the optical fiber can monitor or detect optical signals with a high degree of integration and high optical coupling efficiency.
