Two-dimensional multi-beam steering for parallel free-space optical communication based on a silicon nitride optical phase array
We propose and demonstrate a broadband two-dimensional multi-beam optical phased array (MOPA) with four beams based on a Butler matrix on a silicon nitride (Si3N4) platform. A beamforming network utilizing cascaded Butler matrix splitting arrays has been proposed to scale up the MOPA for the first t...
