Schematic drawing of the magneto-optical isolator with Si waveguides.
Image of the fabricated sample of isolator with Si waveguides, on which a slab of Ce:YIG is bonded.
Setup for the measurement of isolator operation.
Measured transmission spectra for different propagation directions. Light transmits the sample from left to right in CW direction and from right to left in CCW direction. The solid lines show the transmission spectra measured with external magnetic fields applied to the interferometer arms in antiparallel direction. The dashed lines show the transmission spectra measured without magnetic fields. (a) Fifth and (b) fourth samples from the top, shown in Fig. 2, are measured.
Calculated transmission loss of the designed isolator. The solid lines show the transmission spectra without any dimensional error , incurred during bonding. The dashed lines show the transmission spectra with an assumed dimensional error of .
