| description | An optical coupler in a photonic chip is configured to couple an optical port to an array of optical phase shifters in the chip. An optical amplifier module is optically coupled to a portion of the chip to receive phase shifted optical waves, and is configured to: provide, after propagation of the phase shifted optical waves through different respective gain regions, amplified optical waves that optically interfere with each other starting at an emission plane to form an optical phased array output beam, and provide an arrangement of the gain regions such that (1) at least two phase shifted optical waves propagating through adjacent gain regions have optical path lengths between the optical port and the emission plane that are substantially equal to each other, and (2) a pitch of the gain regions is substantially equal to a pitch of the amplified optical waves at the emission plane. |
