Key Details

Uses 5-layer dielectric heterostructure with magneto-optic material

Leverages transverse magneto-optical Kerr effect for non-reciprocity

Strategically placed ring resonator redirects backward propagation

Achieves 20dB isolation ratio with 0.08dB insertion loss

Compatible with low-gyrotropy magneto-optic materials

Unidirectional light propagation in dielectric waveguides

This paper proposes an integrated optical isolator made of dielectric materials, using magneto-optic effects to break reciprocity. It achieves over 20dB isolation ratio between forward and backward light propagation directions with minimal losses.
