Abstract
The spectrum responses of fiber Bragg gratings controlled by in-fiber light were demonstrated. Fiber Bragg gratings coated with carbon films were heated with in-fiber high-power 910-nm diode laser light leaked through fiber cladding for resonance wavelength tuning, spectrum stretching, and compression.
