  • Electro-optical payload for high-bandwidth free space optical communications
    Patent number: 9379815
    Abstract: An electro-optical payload for free space optical communication includes: a plurality of optical beam expanders, each for receiving a respective optical signal; an optical cross-connect switch for directing respective optical signals to respective optical output signals; an electrical-to-optical conversion circuit coupled to an input of the optical cross-connect switch for converting an electrical signal to an optical signal for inputting to the optical cross-connect switch; an optical-to-electrical conversion circuit for converting an optical signal output from the optical cross-connect switch to an electrical signal; and an electrical regeneration circuit including a second optical-to-electrical conversion circuit coupled to an output of the optical cross-connect switch and a second electrical-to-optical conversion circuit coupled to an input of the optical cross-connect switch for converting an optical out signal of the optical cross-connect switch to an electrical signal.
