Second-order filter response from parallel coupled glass microring resonators

Second-order filter response from parallel coupled glass microring resonators

Ring resonators are coupled in parallel in order to obtain a second order type of wavelength response. The phase relationship between the rings determines the details of the spectral response. The rings used in the experiment have radii of 25 μm and are fabricated from compound glass having an index...

Zusammenfassung:Ring resonators are coupled in parallel in order to obtain a second order type of wavelength response. The phase relationship between the rings determines the details of the spectral response. The rings used in the experiment have radii of 25 μm and are fabricated from compound glass having an index of 1.539. Several resonances are observed to have double peaked box-like response.
