The effect of waveguide width on the propagation of self-collimated beams in photonic crystals is studied using the finite-difference time-domain method. It is shown that, to obtain good transmission, it would be better to keep the waveguide width above a minimum value. It is also shown that waveguide intersections based on the effect of self-collimated beams can provide high throughput and low cross talk simultaneously within a relatively wide bandwidth.
