摘要：
The invention relates to a device for determining a refractive index or a hydrophone, which contains at least one waveguide (10) with a core (11) and cladding (12) surrounding the core (11), wherein the cladding (12) is at least partly removed in at least one first longitudinal portion (21) and the core contains at least one fiber Bragg grating (4) in at least one second longitudinal portion (22), wherein at least one part of the surface (210) in the first longitudinal portion (21) is provided with nanoparticles (3) and the device furthermore contains an apparatus for detecting the intensity of the light reflected or transmitted by the fiber Bragg grating (4). Furthermore, the invention relates to a method for producing and using this device.
