Abstract

A wavelength-switchable erbium-doped fiber ring laser is demonstrated and reported. The erbium-doped fiber net gain of the fiber laser is modified by controlled heating of a Long Period Fiber Grating (LPFG) inserted into the laser cavity. The rejection band of the LPFG is altered in the resonant wavelength and loss according to the exposed temperature and consequently, the operating wavelength of the fiber laser can be switched from a single wavelength operation at 1563 nm to a simultaneous operation at 1527 and 1563 nm. The laser system can be used as a temperature fiber sensor as well.
