Abstract

The oscillation wavelength degeneracy at the edges of the Bragg reflection band is a major problem in index-coupled DFB1,2 lasers. One solution to this problem. is the use of antire flection/high- refleetion (AR/HR)-coated facets. This, however, causes a yield problem associated with the uncertainty of the facet phases.1 Another solution is the incorporation of a λ/4 or corrugation-pitch modulated phase shift.2
