Abstract
Embodiments of a photonic link having low residual carrier, for use in transmitting information between an electronic signal source and an electronic signal receiver is provided. The photonic link comprises a transmitter, which uses angle modulation, and two threshold optical frequency discriminators that are biased to provide large even-order distortion, an optical signal receiver and at least one transmission fiber to transmit complementary modulated signals between the transmitter and the optical signal receiver, whereby the optical signal receiver reconstructs the complementary modulated signals into the electronic information for acceptance by the electronic signal receiver. Exemplary methods of transmitting information are also provided.
