Abstract
A wavelength tunable laser includes a gain section, a grating section, and an isolation section. The gain section generates and modulates an optical signal. The grating section is positioned adjacent to the gain section, and the isolation section is disposed between the gain section and the grating section. The isolation section impedes conduction of an electrical current between the gain section and the grating section.
