Abstract
The stable two-mode operation of a 4-sections semiconductor laser emitting at 1.55 μm is demonstrated and analysed. The two-mode operation only depends on the current feed in the Bragg section. The characterization of the two-mode laser operation exhibits the possibility of terahertz wave generation by photomixing using this device. An interpretation of the two-mode regime involving a saturable absorber is discussed.
