Unidirectional Wave Propagation in Low-Symmetric Colloidal Photonic-Crystal Heterostructures
We show theoretically that photonic crystals consisting of colloidal spheres exhibit unidirectional wave propagation and one-way frequency band gaps without breaking time-reversal symmetry via, e.g., the application of an external magnetic field or the use of nonlinear materials. Namely, photonic cr...
