Optimal circle packing
WebApr 6, 2024 · Photonic lanterns (PLs) rely on a close packed arrangement of single-mode fibers (SMFs), which are tapered and fused into one multimode core. Topologically optimal circle packing arrangements have been well studied. Using this, we fabricate PLs with 19 and 37 SMFs showing tightly packed, ordered arrangements with packing densities of … WebNov 12, 2012 · Packing efficiency The algorithm works quite poorly on identically-sized circles (it cannot find the famous honeycomb pattern for 20 circles in a square), but pretty well on a wide distribution of random radii. Aesthetics The result is pretty ungainly for identical-sized circles.

WebRandom close packing of spheres in three dimensions gives packing densities in the range 0.06 to 0.65 (Jaeger and Nagel 1992, Torquato et al. 2000). Compressing a random packing gives polyhedra with an average of 13.3 faces (Coxeter 1958, 1961). For sphere packing inside a cube, see Goldberg (1971), Schaer (1966), Gensane (2004), and Friedman.
