چکیده

A simple fiber-Bragg-grating (FBG) sensor system based on a linear-cavity fiber laser is proposed and experimentally demonstrated. The lasing wavelength shift resulting from the temperature variation on this sensing element is discriminated by two FBGs. These two FBGs, acting as wavelength discriminators, are used to increase the real-time measurement range for monitoring the temperature variation. © 2003 Wiley Periodicals, Inc.

A tunable and switchable single-longitudinal-mode dual-wavelength fiber laser with a simple linear cavity.

A simple linear cavity erbium-doped fiber laser based on a Fabry-Perot filter which consists of a pair of fiber Bragg gratings is proposed for tunable and switchable single-longitudinal-mode dual-wavelength operation. The single-longitudinal-mode is obtained by the saturable absorption of an unpumed erbium-doped fiber together with a narrow-band fiber Bragg grating. Under the high pump power (>...
