Different from previous investigations, Yiqi Zhang and co‐workers (see article number 2000015 ) develop a new kind of Dirac photonic lattice that possesses type‐II Dirac cones in the band structure intrinsica
As an optical analogy, type㊣I Dirac photonic lattices have been also designed. Here, type㊣I Dirac cones are reported in Lieb﹍ike photonic lattices composed of identical waveguide channels, and the anisotropy of the band structure is due to neither the refractive index change nor the ...
