Abstract:
1. A photonic link having low residual carrier, for use in transmitting information between an electronic signal source and an electronic signal receiver, said photonic link comprising: a transmitter to accept electronic information from said electronic signal source and to transmit optical signals, said transmitter comprising a first and second non-linear threshold electronic to optical converter to convert said electronic information into optical signals and wherein said non-linear threshold electrical to optical converters are biased to provide large even-order distortion; said first non-linear threshold electrical to optical converter being complementary to said second non-linear threshold electrical to optical converter, to provide a first and second modulated signal, said first modulated signal being complementary to said second modulated signal; an optical signal receiver; and at least one optical transmission path to transmit said complementary modulated signals between said transmitter and said optical signal receiver, whereby the optical signal receiver reconstructs said complementary modulated signals into said electronic information for acceptance by the electronic signal receiver.
