The Development of the Wavelength Multiplex Fiber Laser by the Oscillation Wavelength Automatic Optimization

Abstract

This recerch aimed at the high output of FL by the multiplexing of the plural laser output. Plural Er-FLM that doesn't choose an oscillation wavelength automatically optimize of AWG coupler transparent wavelength by incorporate an AWG coupler in a resonator. It is multiplexed plural Er-FLM by one single mode fiber. When I use this method, it is multiplexed plural Er-FLM by one single mode fiber and developed FL of the high output and the brightness.
As a result, oscillation wavelength of Er-FLM automatically optimize of AWG coupler transparent wavelength in the 1540.2nm to 1562.6nm every about 3.2nm. Output power that multiplexed eight set Er-FLM is 81.3mW. This is 8 times of the single Er-FLM output (10mW). Consequently, scaling law of the FL output multiplexed a wavelength for the number of the input ports was passed.
