Temperature Sensor Using a Multiwavelength Erbium-Doped Fiber Ring Laser

الملخص EN

A novel temperature sensor is presented based on a multiwavelength erbium-doped fiber ring laser.

The laser is comprised of fiber Bragg grating reflectors as the oscillation wavelength selecting filters.

The performance of the temperature sensor in terms of both wavelength and laser output power was investigated, as well as the application of this system for remote temperature measurements.
