Abstract
This paper describes the use of a Nonlinear Loop
Mirror to achieve wavelength and power stabilization in a three
wavelength Erbium doped fiber ring laser. The laser uses three
fiber Bragg grating reflectors as the oscillation wavelength
selecting filters. The influence of the length of the Nonlinear Loop
Mirror (NOLM) on the laser stability both in terms of
wavelength and laser output power was investigated. The laser
performance was improved by changing the length of the Loop
Mirror to an optimal length and three simultaneous wavelength
oscillations with acceptable power and wavelength stability were
achieved.
