  • OPTO-ELECTRONIC DEVICE
    Publication number: 20240039250
    Abstract: The present invention concerns an optoelectronic device D such as a Semiconductor optical amplifier (SOA) working in a continuous wave condition and able to amplify high frequencies optical signals. The optoelectronic device D comprise an active zone I (such as SOA) with a slab (3) in a direct bias working in a continuous wave and a taper zone (II) connected to the active zone (I).

  • DISTRIBUTED FEEDBACK LASER WITH COMPLEX COUPLING
    Publication number: 20230307888
    Abstract: A distributed feedback laser (DFB) is a type of laser diode in which the active region of the device contains a periodically structured element or diffraction grating, which may include periodic changes in refractive index that cause reflection back into the laser cavity. Conventional DFB lasers used in optical networks may exploit either loss-modulated or index-modulated gratings. In the case of complex-coupling, index-modulated and loss-modulated gratings may be combined together.
