Abstract:

A binary photonic delay line (PDL) module is proposed that gives balanced or equal gain/loss switched states. The module is based on a reflective and symmetric geometry and is adjustable to a wide range of time delays. Theoretical analysis as well as experimental demonstration of the proposed PDL architecture is performed. Issues such as electrical signal-to-noise ratio and relative output signal power between the two PDL settings are discussed.
