  The analytic specifications of photonic lattices with fractional revival (FR)
and perfect state transfer (PST) are reviewed. The approach to their design
which is based on orthogonal polynomials is highlighted. A compendium of
analytic models with PST is offered. New results on their FR properties are
included. The nearest-neighbour approximation is adopted in most of the review;
one analytic example with next-to-nearest neighbour interactions is also
presented.
