Abstract

A system and method for regenerating optical signals comprising a clock recovery circuit coupled to a transmission line, a first optical gating device having an input port coupled to the transmission line and a clock port coupled to the clock recovery circuit, and a second optical gating device having an input port coupled to a continuous wave (CW) laser and a clock port coupled to the output of the first optical gating device, wherein the optical gating devices may be terahertz optical asymmetric demultiplexers (TOADs).
