Abstract:
Speckle reduction in photonic phased array structures can be achieved using a receiver aperture that is configured to provide optical energy through portions of at least one optical network. The optical network is in communication with phase-controlled elements of at least one array of phase-controlled elements. Optical energy is coupled through a first portion of the optical network to a first optical detector in a detector structure, and optical energy is coupled through a second portion of the optical network to a second optical detector in the detector structure different from the first optical detector in the detector structure.
