Abstract
A laser comprises a front mirror (FM), a gain section coupled to the FM, a phase section coupled to the gain section such that the gain section is positioned between the phase section and the FM, and a back mirror (BM) comprising an interferometer and coupled to the phase section such that the phase section is positioned between the BM and the gain section. A method comprises splitting a first light into a second light and a third light, reflecting the second light to form a second reflected light, reflecting the third light to form a third reflected light, and causing the second reflected light and the third reflected light to interfere and combine to form a combined light to narrow a reflectivity peak spectrum width.
