Abstract
A method of reducing undulation in the L vs. I curve of a laser which uses a fiber grating is presented. The spectral width of the fiber grating is made larger than the Fabry-Perot spacing of the laser cavity. As a result, as the laser shifts between harmonics due to laser functioning (e.g., laser drive current, laser aging, temperature change, or mechanical stress), the fiber grating is able to respond linearly because of a large spectral width.
