Photonic bandgap fibers have a critical constraint determined by wavelength. The principle of scale invariance requires that features remain unchanged even as the scale of an object changes. This paper introduces a new concept for fractal photonic crystal fibers integrating these two. Our simulation confirmed single-mode transmission is possible for a fiber whose core diameter exceeds 35 times the wavelength.
