One-way total reflection with one-dimensional magneto-optical photonic crystals
The authors show that one-dimensional magneto-optical photonic crystals can achieve one-way total reflection. The unit cell of the crystal, which consists of two bismuth iron garnet layers with opposite magnetization and one Si O 2 layer, is designed to simultaneously break time-reversal, spatial in...
