| Zusammenfassung: | An optical fiber device (31) comprises a core (35) and a cladding (33), the core (35) being made of an optical material having a refractive index n1, and the cladding being made of an optical material having a refractive index n2, end (34) of the optical fiber from which light radiates forming a plane that is inclined to the fiber axis by an angle theta , a light reflective layer being formed at least on the outer periphery of said radiating end, and the two refractive indices n1 and n2 satisfying the following relation (1): n1-n2>/= 0.01 (1). |
