Abstract

We propose on-chip optical isolators that provide large isolation ratios. The isolation mechanism is based on the interplay between magneto-optical effects and resonant delocalization. Our analysis predicts large isolation ratios in the range of -45 to -55 dB between forward and backward propagating optical beams. Both analytical and numerical results are presented, and fabrication feasibility is also discussed. © 2012 Optical Society of America.
