Design principles of long-term analog RF memory based on fiber-optics and RF photonics techniques

Abstract

We proposed and validated experimentally four advanced principles for circuit optimization of long-term fiber-optic analog RF memory: distributed structure of low-power emitters based on dense wavelength division multiplexing, multicore optical fiber as retarding medium, two-stage processing including optoelectronic repeater unit, and optical recirculation time-delay circuit.
