Abstract
between the first and second resonators and. Similarly, a second polarization converter for converting a TE-polarized light to a TM-polarized light is provided on the second waveguide between the first and second resonators and. Among the light propagating through the first waveguide, the TE-polarized light with wavelength λr is introduced from the first resonator into the second waveguide, whereas the TM-polarized light is converted to a TE-polarized light by the first polarization converter and then introduced through the second resonator into the second waveguide.
