摘要： The invention relates to a wavelength-maintaining purely optical signal regenerator to which degraded optical signals with a high data rate are transmitted and regenerated without opto-electronic or wavelength conversion using compact, non-linear semiconductor components with low power consumption. Said regenerator comprises: an optical clock regeneration stage (2) which generates synchronized stable optical reset clock pulses for the data signal (1); at least one semiconductor component that is non-linear with reference to the transmission characteristics for the data signal (5,9); means for transmitting part of the degraded data signal (1) to the clock regeneration stage (2) being configured in such a way that a timed optical reset to achieve transparency occurs; a time-slice control unit (3) which is connected upstream of the semiconductor component (5,9) and defines a sequence of data bits in the time gap between two respective clock pulses, means for transmitting the other part of the degraded data signal (1) to the semiconductor component (5,9) at a power at which the semiconductor component (5,9) relaxing from the condition of transparency exhibits a nonlinear transmission characteristic for the data signal, and a blocking unit (6) that is connected downstream of the semiconductor component (5,9) and that removes the reset clock pulses from the data signal path.

摘要： 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.
