A photonic bandgap (PBG) is a range of frequencies, in which no propagating states of light exist. PBGs can be engineered by dielectric arrangements that are structured on the length scale of the light’s wavelength. Many biological species, from plants to insects, use this mechanism to produce structural colour through periodically ordered and amorphous networks. These nets can be characterized by their coordination number - the number of edges joined at each vertex. Ordered nets are well understood but show an intrinsically anisotropic optical response. The diamond net with a coordination number of 4 exhibits a large bandgap. A Metropolis Monte-Carlo algorithm is an established method to gradually transform the diamond net into a disordered photonic structure. However, nature employs other network geometries, such as the chiral gyroid, which has a coordination number of 3. Here, we alter the conventional bond bending energy in the Monte Carlo algorithm to enable a generalization to arbitrary coordination numbers. We investigate the statistical properties of amorphous diamond nets. We derive the right simulation parameters to obtain similar degrees of disorder by comparing the nets generated with the established and our new bond energy.
