Abstract
Embodiments herein describe a waveguide crossing that permits at least two optical signals to cross in two different directions. For example, one optical signal can propagate from left to right through the center of the waveguide crossing at the same time a second optical signal propagates up and down through the center of the crossing. In one embodiment, a circular disc is disposed at the center of the waveguide crossing through which the two (or more) optical signals pass. The shape of the circular disc can provide low insertion loss as the respective optical signals propagate between respective pairs of waveguides, as well as minimize cross talk between the two optical signals.
