Coherent electrical serdes in the thz range

Abstract

Transport networks, network elements, and methods of use are described herein, including a network element comprising serializers, modulators, and antennas. The serializers receive parallel baseband signals and multiplex the parallel baseband signals to generate pairs of serial baseband signals. The modulators receive the serial baseband signals, up-convert the serial baseband signals to generate pairs of intermediate signals, and combine the pairs of intermediate signals into antenna feed signals, each having an in-phase (I) component and a quadrature (Q) component based on the pair of intermediate signals. The antennas receive the antenna feed signals, generate radiated signals based on the antenna feed signals, and couple the radiated signals into hollow waveguides. The radiated signals are radiated electromagnetic waves having a frequency in a range between
