Abstract
A radio frequency generator has first and second lasers configured to emit first and second optical outputs; a reference module configured to receive at least part of the first and second optical outputs from the first and second lasers; a control module connected to the first and second lasers and to the reference module; and an optical-to-electrical (O/E) converter configured to process optical signals, originating from the first and second single-frequency lasers, to provide a radio frequency output.Another radio frequency generator has a control module; and a reference module connected to the control module. The reference module includes a photonic integrated circuit (PIC) having first and second single-frequency lasers configured to emit first and second optical outputs; an unbalanced Mach-Zehnder interferometer (UMZI) with first and second 3×3 optical splitter/combiners; first and second peripheral splitter/combiners; and an output splitter/combiner.
