One-way total reflection with one-dimensional magneto-optical photonic crystals
One-way total one-dimensional magneto-optical photonic crystals
2015/8/11
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 ...
Suppressing the effect of disorders using time-reversal symmetry breaking in magneto-optical photonic crystals: An illustration with a four-port circulator
Magneto-optics Photonic crystals Optical resonances Channel add/drop fi lters Optical circulators Nonreciprocity
2015/8/11
In integrated optical systems, nonreciprocal elements are indispensable devices that eliminate multi-path reflection between components. To miniaturizing these devices down to a single-wavelengt...
Optical circulators in two-dimensional magneto-optical photonic crystals
Optical circulators two-dimensional magneto-optical photonic crystals
2015/8/11
We propose an optical circulator formed of a magneto-optical cavity in a 2D photonic crystal. With spatially engineered magnetic domain structures, the cavity can be designed to support a pair of coun...
