Tunable, polymeric core, fiber bragg gratings |
摘要 |
Provided are polymeric or polymeric and glass optical fiber devices which have a tunable wavelength response in a polymeric fiber Bragg grating. An optical fiber is formed having a tubular cladding of a first polymeric or glass composition having a first index of refraction, wherein the cladding has a longitudinal axis. A core of a second polymeric composition is within the cladding and extends along and around the longitudinal axis. The second polymeric composition has a second index of refraction which is greater than the index of refraction of the first polymeric composition. A Bragg grating having a plurality of spaced grating elements is formed in the core. The arrangement then has a means, such as a heater, for changing the spacing between the grating elements.
