Claim 10:
11. A method comprising:
transmitting or receiving optical signals using a photonic integrated circuit comprising an optical phased array, the optical phased array comprising multiple unit cells, each unit cell comprising (I) multiple antenna elements that transmit or receive the optical signals, (ii) multiple signal pathways that transport the optical signals to or from the antenna elements, and (iii) multiple phase modulators that modify phases of the optical signals being transported through the signal pathways;
wherein, in each unit cell, a first subset of the antenna elements is oriented in a first direction and a second subset of the antenna elements is oriented in a second direction opposite the first direction; and
wherein, in each unit cell, at least some of the signal pathways have an “H”configuration.
