Abstract

We abstract optical waveguide meshes into graph representations to solve practical light
distribution problems, leveraging structures and algorithms from graph theory. One of
the substantial problems is single input-output signal routing inside the meshes. Whilst
respecting physical restrictions regarding the directional flow of light, three types of
graph representations are compared in terms of feasibility for solving this problem. Of
the three types, the directed graph with eight artificial nodes proves to be superior. A
representation of this kind takes us one step closer to a fully programmable optical core
with complex functionalities, especially in photonic meshes with feedback paths.
