Abstract
A phased antenna array includes an array of antenna elements, and an electro-optic (EO) readout circuit coupled to the array of antenna elements. The EO readout circuit includes an optical source having a first wavelength division multiplexer (WDM) configured to generate an optical carrier signal including beam carrier wavelengths, a first EO modulator configured to modulate a signal from an antenna element based upon the optical carrier signal, a second WDM coupled downstream from the first EO modulator, and optical-to-electrical converters coupled downstream from the second WDM. The second WDM is configured to multiplex each modulated beam carrier wavelength to a respective optical-to-electrical converter.
