    "abstract": "We study the existence and stability of cnoidal periodic wave arrays\npropagating in uniform quadratic nonlinear media and discover that they become\ncompletely stable above a threshold light intensity. To the best of our\nknowledge, this is the first example in physics of completely stable periodic\nwave patterns propagating in conservative uniform media supporting bright\nsolitons.",
