Abstract:
Feeding a plurality of antenna elements of an array antenna, involves receiving at a photonic substrate at least one transmit modulated optical carrier (TMOC) signal. The TMOC signal is communicated to an array level photonic integrated circuit (ALPIC) disposed on the photonic substrate where one or more optical processing operations are performed involving the TMOC signal to obtain a plurality of element-level optical carrier (ELOC) signals. These ELOC signals are communicated from the ALPIC to a plurality of conversion locations distributed on the photonic substrate. Photodetectors respectively provided at the conversion locations convert each of the ELOC signals to an element-level modulated radio frequency (ELMRF) signal. The ELMRF signal are coupled from each photodetector respectively to one of the plurality of antenna elements.

Claim (Index 17):
An optical interposer for a plurality of antenna elements of an array antenna, comprising:\n a photonic substrate on which is disposed:\n an optical interface configured to facilitate an optical communication link with a remote optical signal source; \n an array level photonic integrated circuit (ALPIC) which is optically coupled to the optical interface, the ALPIC configured to perform at least one optical processing operation on a transmit modulated optical carrier (TMOC) signal received at the optical interface; \n a plurality of photodetectors disposed at a plurality of conversion locations distributed on the photonic substrate; \n a plurality of element-level optical waveguides configured to optically distribute a plurality of transmit element-level optical carrier (ELOC) signals from the ALPIC to the plurality of photodetectors; \n wherein the plurality of photodetectors are configured to convert each of the transmit ELOC signals to a transmit element-level modulated radio frequency (ELMRF) signal, and a plurality of RF couplings are provided to communicate the transmit ELMRF signals respectively from the plurality of photodetectors to the plurality of antenna elements.
