Photonic packet buffers are essential components in photonic packet switching systems. We present a wavelength routing-based photonic packet buffer based on a state-of-the-art arrayed-waveguide grating (AWG) multiplexer. We show how this new packet buffer can be effectively used in the implementation of photonic packet switching systems. We also propose and examine two different photonic packet switch architectures.
