We derive that, in all-pass
(unity amplitude transmittance or reflectance) one-dimensional layered
structures, the tangent of the group-propagation angle, the group delay,
and the stored energy are approximately proportional. Thus photonic
crystal superprisms and spatial dispersion in nonperiodic photonic
nanostructures are generally related to wavelength-dependent stored
energy in the stack.
