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 55dB between forward and backward propagating optical beams. Both analytical and numerical results are presented, and fabrication feasibility is also discussed.
