  • SEMICONDUCTOR LASER AND METHOD FOR OPERATING A SEMICONDUCTOR LASER
    Publication number: 20100202487
    Abstract: A semiconductor laser includes an active region designed as a DFB laser and a passive resonator section that is optically coupled to the active region. The active region has a first section with a Bragg grating and a second section with a second Bragg grating that differs from the first Bragg grating. The two Bragg gratings differ from one another such that one and only one main mode of a DFB mode spectrum of the first section overlaps with one of two main modes of a DFB mode spectrum of the second section.
