Certain lattice wave systems in translationally invariant
settings have one or more spectral bands that are strictly flat
or independent of momentum in the tight binding approximation,
arising from either internal symmetries or fine-tuned coupling.
These flat bands display remarkable strongly interacting phases
of matter. Originally considered as a theoretical convenience
useful for obtaining exact analytical solutions of
ferromagnetism, flat bands have now been observed in a variety
of settings, ranging from electronic systems to ultracold atomic
gases and photonic devices. I will review the design and
implementation of flat bands and chart future directions of this
exciting field. In particular I will focus on the field of
photonic lattices. Flatband photonic lattices consist of arrays
of coupled waveguides or resonators where the peculiar lattice
geometry results in at least one completely flat or
dispersionless band in its photonic band structure. Although
bearing a strong resemblance to structural slow light, this
independent research direction is instead inspired by analogies
with “frustrated” condensed matter systems. In this talk, I will
critically analyze the research carried out to date, discuss how
this exotic physics may lead to novel photonic device
applications, and chart promising future directions in theory
and experiment.</span><span style="background-color: rgb(255,
