Nonreciprocal propagation in magnetooptic YIG rib waveguides

In this paper, we describe the experimental results on the nonreciprocal propagation in the magnetooptic YIG rib waveguides. First, we demonstrate the nonreciprocal phase shift in the straight waveguide, and next we confirm the nonreciprocal intensity propagation in the Mach-Zehnder interferometric waveguide with asymmetric arms. These are important for the construction of the differential phase shifter type nonreciprocal devices.
