Abstract

We propose, analyze, and demonstrate the use of a holographic method for cohering the output of a fiber tapped-delay-line (FTDL). We perform a theoretical examination of the phase-cohering process and show experimental results for an RF spectrum analyzer based on a phase-cohered FTDL that shows 50 MHz resolution and bandwidths in excess of 2 GHz. Phase-cohering holography can operate on thousands of fibers in parallel, enabling both fiber tapped-delay-lines and the coherent fiber remoting of optically-modulated RF signals from antenna arrays.
