Abstract
Methods and systems for determining true time delay from each receiving element of an 'active electronically scanned array' (AESA) or a phased array antenna. Embodiments of the invention can include electromagnetic EM elements, optical waveguides, and wavelength selective FGBs are collectively configured as a plurality of dual purpose elements that couples an EM field and uses an induced voltage to change an index of refraction of the optical waveguide's electro-optic (EO) material, where the EO material will also function as a dielectric in an antenna element, where the signals comprising optical signals propagate through EM element acting as phase delay elements, where the measuring system compares the reflected signals with a reference signal with no phase delay to determine said signals phase delay.
