摘要： A divergence angle measurement device that monitors a divergence angle of laser light propagated in an optical fiber having a core and a cladding is provided. The divergence angle measurement device includes: a first photodetector that detects laser light that leaks from the cladding; and a processor that obtains the divergence angle of the laser light propagated in the optical fiber based on a detection result of the first photodetector and power information that indicates power of the laser light propagated in the optical fiber.

摘要： An optical component includes: a first fiber having a first end and a second end; a second fiber having a third end and a fourth end; a third fiber having a fifth end and a sixth end; a first coating layer that covers the cladding of the second fiber and has a higher refractive index than that of the cladding of the second fiber; and a first high refractive index layer that covers part of an outer peripheral surface and an end face of the second fiber. The first high refractive index layer has a higher refractive index than that of the cladding of the second fiber. The outer diameter of the cladding of the first fiber is smaller than that of the cladding of the second fiber. The outer diameter of the cladding of the third fiber is smaller than that of the cladding of the second fiber.
