  • 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.

  • Optical clock recovery device for recovering the clock from an optical signal
    Patent number: 7209666
    Abstract: An all-optical clock recovery system for recovering the clock from a received optical signal with a short response time and without patterning effects includes a first optical clock recovery device adapted to supply a first optical clock signal in response to the received optical signal and a second optical clock recovery device adapted to supply a second optical clock signal in response to the first optical clock signal. Applications include regenerating optical packets in asynchronous optical packet-switched telecommunication networks.

  • Wavelength-maintaining optical signal regenerator
    Publication number: 20070064501
    Abstract: 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.
