Provided herein are optical flow switches, and optical flow switch packages, implemented using photonic switches. The optical flow switch includes a network of photonic switches arranged between input and output ports of the optical flow switch. The network of photonic switches spans two or more reticles, and the two or more reticles may include photonic switching arrangements corresponding to repeated reticle masks or sets of reticle masks. The optical flow switch may be mounted to a glass substrate to form an optical flow switch package.
