Patent number: 11265083Abstract: An apparatus for signal modulation in a point-to-multipoint optical network is configured to modulate a single-wavelength carrier wave before distribution towards optical receivers of a first type adapted for intensity detection and a second type adapted for optical field detection. The apparatus includes a first module configured to modulate the carrier wave by varying the intensity of the carrier wave to represent data intended for the first type of receivers, and by controlling the phase and/or polarization of the carrier wave during selected periods. The apparatus includes a second module configured to modulate the carrier wave by varying the phase and/or polarization of the carrier wave to represent data intended for the second type of receivers, and by varying the intensity of the carrier wave during selected periods.Type: GrantFiled: December 29, 2020Date of Patent: March 1, 2022Inventors: Jochen Maes, Robert Borkowski, Rene Bonk

Patent number: 9853763Abstract: Proposed is an OLT for a passive optical wavelength division multiplex network. The network contains optical transmitters for generating downstream signals of an L-Band, as well as optical receivers for receiving upstream signals of a C-Band. Furthermore, the OLT contains a bi-directional SOA and an optical interface. The optical interface, the SOA, the transmitters and the receivers are optically coupled such that an upstream signal received at the optical interface is firstly provided to the bi-directional SOA and subsequently from the SOA to one of the receivers, and such that a downstream signal generated by one of the transmitters is firstly provided to the bi-directional SOA and then subsequently to the optical interface. The bi-directional SOA has a gain function that is not constant with respect to a wavelength of an optical signal to be amplified. Furthermore, the gain function is maximal for a wavelength located within the C-band.Type: GrantFiled: September 19, 2014Date of Patent: December 26, 2017Assignee: Alcatel LucentInventors: Rene Bonk, Harald Schmuck, Wolfgang Poehlmann
